About PolyGrid®
PolyGrid® precision-expanded polymers from Dexmet are used in ultra-pure filters, most commonly in the semiconductor industry where resistance to high temperatures and caustic chemicals is essential. Other uses include the medical, gas, oil and pharmaceutical industries. However, the flexibility of our expanded plastics allows PolyGrid® to be used in many other applications. Dexmet PolyGrid® is available in most polymers or we can work with your proprietary materials. Dexmet meets Clean Room specifications to Class 10,000.
- Fluoroplastics: PTFE, PFA and ECTFE
- Polyesters (Thermoplastic): PET, PETP, PBTP
- Polysulfones
- Polyvinyls
High Temp Plastics: PTFE (PFOA-free), PEEK, Nylons
A range of standard diamond mesh sizes from .020” to 1.2” is available. The number of openings per square inch can vary from 25 to as many as 11,000, with an open area range from 10% to 90%. The variable open area facilitates lamination with a variety of other materials including those which expand, contract and flex. Designing a precision expanded plastic material with unique characteristics is our specialty. Dexmet’s extensive manufacturing resources can accommodate many variations for plastic materials in a range of finished thicknesses.
PFOA-Free Material:
Dexmet Corporation introduces PFOA-Free PolyGrid® Expanded Fluoropolymers. PFOA (Perfluorooctanoic Acid), is widely used as a polymerization surfactant in making fluoropolymers including PTFE, PFA and FEP. Dexmet provides PolyGrid® without this harmful additive for medical, filtration and food processing applications that require a PFOA-free expanded material.
PolyGrid's® flexibility and its unique properties allow our expanded polymers to be used in a number of applications.
