Abstract:Eight kinds of common sole materials of rubber(isoprene rubber,styrene-butadiene rubber and butadiene rubber),polyethylene,polyvinyl chloride,polyurethane,thermoplastic rubber and ethylenevinyl acetate copolymer were measured using the instrument of attenuated total reflection Fourier transform infrared ...
Figure 2 shows image analysis pictures that include examples of single particles from filters RefEnv1 and Ref7P, which showed matches with two or more different database entries. The polyurethane (PUR) particle from Fig. 2a gave matches with four different clusters: PUR 2, PUR varnish, polyest...
Since mid-1970's, a great effort was made to improve heat and flame resistance of polyurethane foams in response to increasingly demanding standards for the foam used in construction. In the first approach, foams with good fire retardancy were obtained by incorporating halogen and/or phosphorous ...
polyurethane, polybutylene terephthalate (PBT), polyethylene terephthalate (PET), vinyl ester, epoxy, or similar. The curable flowing fluid resin compositions can comprise the resin component and an activator component, such as an accelerator or curing agent. Suitable epoxy resins can comprise blends...
