GENERAL ACETAL PROPERTIES
Acetal is the common name for a family of thermoplastics with the chemical name "PolyOxy-Methylene". Acetal is available in a general purpose copolymer grade, a homopolymer version (Delrin ®), and several filled Delrin ® grades. Acetal provides high strength and stiffness, enhanced dimensional stability, and is easy to machine. As a semi-crystalline material, acetal is characterized by a low coefficient of friction and good wear properties.
SUSTARIN® C MDT ("METAL DETECTABLE") ACETAL GRADE Sustarin® C MDT is a new engineering plastic that provides all of the standard physical properties of acetal, but can be sensed by metal detectors and is FDA compliant.
Sustarin C MDT offers a solution to many food processing and packaging applications. Most of the food products that we consume every day come into contact with different machines during the manufacturing and packaging processes. If just a small part or component from any one of those machines finds its way into the food there can be serious health risks.
SUSTARIN® C MDT has special additives that allow it to be traced by standard metal detectors and removed before causing further contamination. Quality assurance engineers at some of the largest food processing manufacturers in the country have already tested this product and found it to be highly effective.
The important mechanical, thermal and chemical resistance properties remain unchanged in comparison to standard acetal. This engineering plastic is easily machined and has excellent dimensional stability for close tolerance parts. SUSTARIN C MDT complies with FDA regulations concerning direct contact with food.
This material is offered in rods from 1/4" to 8" diameter and sheets from 3/8" to 4" thick in a brilliant BLUE color.
