Profile Extrusion Compounds
Mass transit interiors frequently require profile extrusions as trim pieces to cover seams and exposed edges or to join parts where they come together. Profile extrusion parts are typically sold as complementary accessories to thermoformed parts and are a critical part of interior railcar design because they provide an attractive transition from one thermoformed part to another. Now, profiles can be a more integral part of the interior design adding to the overall aesthetics and not an afterthought.
KYDEX® thermoplastic sheet and KYDEX® profile extrusion compounds are manufactured using the same colorants ensuring color consistency between the thermoformed parts and profile extrusions. SEKISUI SPI supplies the profile extrusion compounds to Plastifab, a Montreal plastic extruder, who works with customers to fabricate custom profile extrusion parts.
KYDEX® P2200 is a high performance thermoplastic profile extrusion compound designed for mass transit interior applications where SMP800C or BSS7239 compliance is required. It meets full flame, smoke, and toxicity requirements. It complements KYDEX® 2200LT sheet.
KYDEX® P88 is a proprietary, high performance profile extrusion compound designed for mass transit interior applications that meets flame and smoke regulations. It complements KYDEX® 6200 sheet.
Benefits beyond aesthetics
Profile extrusion thermoplastic parts contribute much more than refined aesthetic. They also reduce cost, production time, and fuel consumption. Since KYDEX® Thermoplastics have integral color, parts made from them don’t require a secondary finish such as painting. Replacement costs are also lower than traditional materials because KYDEX® Thermoplastics resist chipping, cracking, and discoloration. Furthermore, unlike fiberglass, when parts are eventually replaced, they can be recycled directly into the production stream.
A lightweight and compliant choice
Light weight requirements, toxicity compliance, and environmental concerns have become more common and rigorous. They have spurred sourcing thermoplastics over traditional materials.Thermoplastic profile extrusion parts are lighter than metal and composite profiles and are available in thinner gauges, which means less fuel consumption and more design flexibility for enhanced interior décor.
