Polymer Group product story

PGI materials are being expanded into package trays, hush panels, dash insulators and HVAC ducts.
Polymer Group (PGI) is expanding the use of its substrates to new vehicle components.
Designed to silence interior vehicle noise, the company's Silonyx materials are currently being used in production vehicles by General Motors, Ford and Honda.
Introduced last year in trunk and wheel-well liners, the PGI materials are being expanded into package trays, hush panels, dash insulators and HVAC ducts.
PGI also has enhanced the product offering in highly engineered wheel-well liners with Silonyx 4, a new four-layer product manufactured in a single-step process.
These substrates, made from recyclable polypropylene and polyethylene terephthalate (PET), provide a barrier to absorb sound and reduce noise in the interior compartment of a vehicle.
In addition, the components themselves are recyclable.
PGI developed the one-step manufacturing process that combines the recycled materials with a facing material through multiple layering and needlepunching in a single step.
This one-step process and use of recyclable materials, produces a more cost-effective product.
The high-strength Silonyx materials are lighter than traditional plastic parts, answering the market need for more efficient vehicles that consume less fuel.
