Delrin® 150SA – Homopolymer

Acetal Materials

Acetal Copolymer / Dupont Delrin® 150SA Homopolymer


Which Acetal material should you use? (POM)Large Copolymer Acetal Rod

  • Both Acetal Copolymer and Delrin® 150SA Homopolymer are FDA Compliant
  • Both are very stiff and have excellent dimensional stability
  • Are Self Lubricating, Abrasion Resistance, and Excellent Wear properties
  • Available in Natural, Black and Blue. Custom colors also available.
  • Cuts extremely well with standard cutting tools
  • Delrin® AF (PTFE Filled), Glass Filled, and Specialty Grades Available
  • Delrin® 150SA Homopolymer have similar properties and frequently replaces: Noryl®Nylon®, and PET or PBT materials
  • Acetal and Delrin® are very popular High Tech Performance Plastics

Some reasons to choose Homopolymer vs. Copolymer

Both POM grades have very similar properties. Our clients seem to prefer the Dupont brand name Homopolymer materials because of the superior physical properties. The issues that lead clients to the Copolymer is a slightly lower cost, and the minor inherent center-line porosity in the Delrin® 150SA Homopolymer grade.

Dupont™ Delrin ® is a popular acetal homopolymer brand name and the most commonly used acetal homopolymer.

The Delrin® 150SA is a brand name of Dupont, and it is often referred to as POM-H or Acetal Homopolymer. Common brand or trade names for extruded Acetal sheet and rod materials include: Tecaform® AH, SUSTARIN® C, ZL® 900-C, Pomalux®, Unital®, Mechatec Acetal®, Acetron® and many more.

Why you should use Acetal/ Delrin®

  • Both the Dupont Delrin® and Acetal Copolymer are FDA Compliant
  • They are very stiff and have excellent dimensional stability
  • Are self-lubricating, abrasion-resistant, and have excellent wear properties
  • Cuts extremely well with standard cutting tools
  • Delrin® AF (PTFE Filled), Glass Filled and Specialty Grades Available
  • Delrin® Rod and Plate have similar properties and frequently replace: Noryl®, Nylon and PET materials

Some reasons to choose Homopolymer vs. Copolymer

Both POM grades have very similar properties. Our clients seem to prefer the Acetal over the Homopolymer materials due to the inherent center-line porosity in the Delrin® Homo-polymer version. This means, that along the center of a rod, or the middle of a sheet, there is a band of area with tiny porous holes. This can weaken or cause problems with a finished part, and in extreme cases, you may see blow by or leakage at this center line. While Delrin® is a brand name, it is a POM Homo-polymer.

The most requested and popular item we supply is the Acetal; the POM Copolymer resin made by one of the other big resin manufacturers – like BASF or Celanese/Tacona.

Both Delrin and Acetal are ITAR compliant, and Delrin and Acetal are RoHS compliant.

Blue Metal Detectable Plastic Helps Reduce Food Recalls

Blue Metal Detectable Plastic Helps Reduce Food Recalls

Food Recalls On The Rise?

During the last year, the number and size of food recalls has been staggering. With several major food processors, specifically in the poultry market, recalling massive amounts of product due to contamination, perhaps a change in material is in order, simply changing to a Metal or X-ray detectable plastic material may end recalls for contamination. The cost to change to a metal detectable plastic or x-ray detectable plastic is extremely small in comparison to the cost of these recalls.

What is a detectable Plastic

There are numerous quality high performance plastic materials that are available in Blue, X-ray and Metal detectable versions. These materials are designed with food safety in mind. These materials can assist the food industry and the food processing supply chain in keeping our foods safe. Identifying contaminates in the processing of foods can be made significantly easier with these detectable materials. Food safety should be the priority within the food processing industry. By changing to metal detectable plastic and X-ray detectable plastics, this can become a reality.

Metal Detectable Plastic and X-Ray Detectable Plastics

Here is a recent Press Release detailing the recalls and a rather straight forward and easy solution using detectable plastic.

(Newswire.net — October 10, 2016) Anaheim, CA – Can ‘Blue’ fix food recalls?The year 2016 has seen some staggering food recalls by large food processors. Massive recalls of chicken specifically seem to have happened multiple times. The part that is the most amazing is that the root cause of many of these kinds of recalls is preventable. The specific recalls listed below are all for possible plastic contamination in the food product.

These large food processors should be aware of some simple steps that can totally eliminate these kinds of contaminates from getting into their food products.Metal Detectable Plastic and X-Ray Detectable Plastics. Blue Acetal, Blue UHMW, Blue Nylon and Blue Hydex 4101 UD Blue Plastic Rod

Penny Wise, Pound Foolish

Keeping Food Processing Safe

While using FDA approved plastic materials for conveyor parts and moving components is a standard practice in most food processing plants, many processors use the cheapest available approved materials. This means that many producers are using a natural (white) HDPE, Acetal or other white approved plastic material. While it is safe to use these plastics, occasionally one of these parts gets jammed, breaks or wears to the point where parts can crack and pieces can get into the food processing line.

It Is Plain To See

The first easy step would be to use the same quality FDA approved material, but to buy the Blue metal detectable plastic version of the same approved material. This minor color change in the material makes any contaminates very easy to see with the naked eye. Since there are no food products in these bright blue colors, as long as there are employees looking at the food line, these broken pieces are easy to detect.

I Can See You

Speaking of detect, the big step up for detection of contaminates is to use a FDA approved plastic that is detectable by the X-ray or metal detection equipment already installed in these food processing lines. While these ‘metal detectable plastics’ cost more, they certainly cost less than one recent 4.5 million pound poultry recall.

The goal here is not to point the finger or call any company a ‘bad processor’, but rather to encourage these great food processors to use the ‘best practice’ types of materials to eliminate these monster food recalls.

In September 2016, Tyson Foods recalled 130,000 pounds of chicken nuggets for foreign materials in the product.

http://www.cnn.com/2016/09/27/health/tyson-chicken-nugget-plastic-recall/

“According to Tyson Foods, the plastic material ranged in size from 21mm in length and 6.5mm in diameter and may have come from a round, hard plastic rod used to connect a plastic transfer belt. The firm said the products pass through a metal detector, but the plastic is not detectable to this technology,” the USDA recall announcement said.

Have You Considered Detectable Blue?

Blue Metal Detectable Plastic Materials

Blue Metal Detectable Plastics From Ensinger

Perhaps they could consider using a metal detectable plastic that is detectable by a standard metal detector. Industrial Plastic Supply has supplied this FDA approved Metal Detectable UHMW rod since early 2010. Currently, there are several FDA approved materials that are available in Blue; UHMW, Acetal, Nylon, Polyester and now PEEK. Some of these materials are also available in a ‘triple detection’ version, where it is detectable because of the vivid Blue color, and it is also Metal detectable and X-Ray detectable. One of these new versions is the Ultra-Detectable Polyester rod made by Ensinger® Plastics called Hydex® 4101 UD Blue (FDA Grade Polyester).

In April and May of 2016, Pilgrim’s Pride had a recall totaling 5,550,904 pounds (yes 5.5 million pounds) of poultry do to possible foreign matter contamination.

http://www.fsis.usda.gov/wps/portal/fsis/topics/recalls-and-public-health-alerts/recall-case-archive/archive/2016/recall-027-2016-release-exp3

What is the cost of these huge food recalls?

The cost is staggering. To recall this quantity of food takes a small army of people to identify the possibly contaminated batches of food. Then notification is spread to all the possible distribution and wholesalers. The USDA is normally notified as one more step to notify the public.

Simple method to protect the safety of our food chain using detectable plastic materials

What is the cost to change to a more metal detectable plastic?

This depends on the type of plastic, and the detection method.

Let’s assume that the currently used material is an FDA approved grade of 1″ diameter Natural Acetal rod (a popular performance plastic used in food processing). And let’s assume this material would sell for approximately $2.00 – $2.50 per linear foot.

Changing to a Bright Blue FDA approved grade of Acetal Rod would cost about $3.50 – $4.00 per foot.

Upgrading to a Metal and X-ray detectable plastic that is FDA grade and Blue Acetal plastic rod would cost in the range of $8.25 – $9.00 per foot.

A recall of 100,000 pounds of poultry is, of course, significantly more expensive than upgrading the plastic materials in the food processing plant. Consider the upgrade an inexpensive insurance policy against these kinds of monster recalls, with a simple change to metal detectable plastic materials.
