The present invention provides a glass mat thermoplastic comprising a glass mat impregnated with an engineering thermoplastic polyurethane etpu having a t g of at least 50 c.
Etpu mat patent.
The glass mat thermoplastic can be prepared for example by a contacting a continuous glass mat with etpu film or sheet or between etpu films or sheets with sufficient pressure and heat to form a multilayered.
Thermoplastic polyurethane tpu is any of a class of polyurethane plastics with many properties including elasticity transparency and resistance to oil grease and abrasion technically they are thermoplastic elastomers consisting of linear segmented block copolymers composed of hard and soft segments.
The present invention provides a glass mat thermoplastic comprising a glass mat impregnated with an engineering thermoplastic polyurethane etpu having a t g of at least 50 c.
A process for forming a shaped three dimensional article comprising the steps of deforming an intermediate form 10 including a plurality of thermoplastic elongated members that are initially movable relative to each other while displaceably clamping the intermediate form during the deforming in such a way that while a force is applied for deforming the intermediate form the.
The glass mat thermoplastic can be prepared for example by a contacting a continuous glass mat with etpu film or sheet or between etpu films or sheets with sufficient pressure and heat to form a multilayered structure which contains a wetted out glass mat layer sandwiched between an etpu layer and a glass mat layer b thermoforming or compression molding the multilayered structure with.
