Press Release Summary:
CelanexÂ® polybutylene terephthalate (PBT) copolymer binder, which melts at 147Â°C, creates all-polyester hood and trunk liners in non-reactive, thermal operation. It meets European recyclability regulations and is used in powdered form to fuse mat of polyethylene terephthalate staple fibers that melts at 250-257Â°C. Material bonds various other fibers in felts or fabrics and can be fabricated as staple fiber, sheet, or film or coextruded over PBT fiber.
Original Press Release:
Low-Melt Polyester Binder from Ticona Forms Lower-Weight, Recyclable Auto Headliners
Weigh Less than Cotton Shoddy or Glass Fiber-Phenolic Liners; Meet European Recyclability Regulations
Summit, New Jersey; Kelsterbach, Germany, April 26, 2004 - A new low-melt polyester binder material from Ticona, the technical polymers business of Celanese AG (NYSE: CZ; FSE: CZZ), is being used to create all-polyester auto headliners, hood liners and trunk liners that weigh significantly less than traditional liners made with cotton shoddy or glass fibers impregnated with phenolic resin. The all-polyester liners meet European recyclability regulations, while phenolic-based liners do not.
The Celanex ® polybutylene terephthalate (PBT) copolymer binder melts at 147°C and is used in powdered form to fuse a mat of polyethylene terephthalate (PET) staple fibers that melts at 250° to 257°C. The all-polyester liners are formed in a non-reactive, thermal operation. Phenolic-based liners must be heated sufficiently to allow the phenolic resin to react and adequately cure.
"Initial trials indicate that polyester headliners made with Celanex ® PBT binder material give automakers a range of essential benefits, including better thermal and sound insulation and weight reduction compared to phenolic-based liners," says Kari Karandikar, Marketing Specialist. "The all-polyester liners have comparable stiffness to those made with phenolic resin."
The versatile Celanex ® PBT binder material has many other potential applications. It can be used to bond a variety of fibers in felts or fabrics. It also can be fabricated as staple fiber, sheet, or film, or coextruded over PBT fiber. These forms present many possibilities. For example, if standard PBT and Celanex ® PBT binder material fibers are commingled and heated above 147°C, the Celanex ® fibers will bind the mass together.
