Recent Advance on Reaction Injection Molding of Polydicyclopentadiene;

Development of reaction injection molding nylon 6

Polydicyclopentadiene (PDCPD) is a novel engineering material synthesized by reaction injection molding (RIM) method and such reaction mechanism is ring-opening metathesis polymerization.

Study on preparation of poly-dicyclopentadiene by reaction injection moulding;

A series of polyurethane -urea elastomers were prepared at the reactant temperatures of30, 40,50 and 60℃, by a reaction injection moulding (RIM) mini-machine.

The phenomena of reaction induced mixing in reaction injection moulding has been analysed theoretically.

The V-type metering system which can infinitely adjust the ratio is developed based on the analysis and compari-sion of the various types of polyurethane metering systems and the performance characteristics of self-developed reaction injection molding machine.

Study on Air Entrainment in RIM Mold Filling;

This paper introduces reaction injection molding, including RIM equipment, materials, processing parameters, mold and product design etc.

In this paper, the world production of PUR industry is described,including raw material, production and consumption of PUR,technical advances of PU foam,such as chlorofluorocarbon (CFCs) substitution technologies, flame retardant PU foams and Polyurethane Reaction Injection Molding (PU-RIM) and development of domestic polyurethane industry.
