Polymer Group Inc. Introduces PET Fabrics for Plastic Injection Moulders

Polymer Group, Inc. is to make commercial available new engineered materials offering benefits for injection moulders in a wide range of automotive, and other recreational and residential applications.

The new, 100 percent-recyclable polyester (PET) fabrics are used as a backing material in the one-step injection moulding process, which is increasingly being used by auto parts manufacturers for interior trim applications.

Laminated to knit facing materials for use in the injection moulding process, these new lighter fabrics offer numerous benefits over traditional needlepunched fleece synthetic fabrics in the manufacturing process. In addition, these new fabrics help increase interior space in automobiles and improve acoustics.

“”These new spunlace fabrics from PGI can help automotive parts manufacturers increase the efficiencies of their manufacturing operations in the one-step injection moulding process, reduce quality defects and potentially save on labour costs,”” said Gerry Rumierz, PGI’s Director of Sales, Automotive. “”They are easier and less cumbersome to work with than needlepunch fabrics and also less expensive to ship.””

The new fabrics are made with a spunlace manufacturing process that maintains elongation properties of the fibres in both machine and cross machine directions for enhanced performance during moulding. As a result, the mould barrier fabric easily conforms to the shape of the mould while maintaining structural integrity and barrier properties.

PGI developed the new family of mould barrier fabrics in response to a growing demand from luxury car manufacturers for technical fabric coverings for use in moulded interior parts, such as pillars, door trim and panels and trays, to enhance the appearance and add value for consumers. The trend, which began in Europe, is now expanding into the United States.

“”We see a wide range of applications for these new spunlace materials moving beyond automotive to home and office furnishings, buses, trains, airplanes, boats, recreational vehicles, race cars, off-road vehicle and tractors, and even video gaming and home audio theaters,”” Rumierz said.

PGI’s mold barrier fabrics meet automotive performance standards for physical properties, content and application. Fabrics are available in a variety of weights to meet a range of temperatures for high- and low-pressure injection moulding. Currently produced in white, the company also has the capability to provide coloured materials.
