Linwood, Pennsylvania-Foamex International Inc. has a new acoustic foam line for automotive uses which, it claims, "reduces passenger compartment noise with advanced polyurethane foam technology."
The new material, called Qylite foam, offers Tier I and OEM design engineers a choice in acoustic materials with differing acoustical functions, a statement from Foamex continued. These include sound absorption, barrier/decoupler systems, and sealing to enhance performance and control vehicle weight and cost.
Qylite foam has "excellent sound absorption," and is easy to handle and install, with long-term stability. Components are also recyclable, said Foamex-which is at present in Chapter 10 bankruptcy protection.
"These new products give design engineers choices and advantages over products already in the marketplace, " said Vinnie Bonaddio Foamex's senior vice president of its Technical Products Group, in a 22 May announcement.
Bonnadio added that Qylite's acoustic performance "will not be adversely affected by stress and vibration."
A range of Qylite materials is available: Qylite 100 is an ultra-lightweight, supersoft polyurethane dash insulator decoupler, made with Foamex's variable pressure foaming (VPF) manufacturing process and proprietary chemistry.
Qylite 300 foam is a thermoformable dash insulator also made using the VPF process, while Qylite 400 foam gives high-performing sound absorbers with competitive pricing.
Qylite AVT combines mechanical properties including low force to compress with excellent damping performance, Foamex said.
These materials can be enhanced by various fabrication and post-processing technologies, and gives synergies with other materials in layered composites, made with Foamex's flame-lamination technology.
In addition to dash insulators, the foams can be used for hood insulators, floor carpet underlay, door panel absorbers and headliner laminate absorbers. Other uses include seat strainer/barrier/decouplers or absorbers, luggage compartment acoustical components, quarter panel trim absorbers and sound absorption for engine beauty shields, said the manufacturer.
Foamex points out that it can also custom-engineer new materials and composites to meet a customer's specific application requirements.
