Keywords: liquidcrystalpolymer; injectionmolding; moldingtechnology industry industry have developed biodegradable plastics in Japan Contest Luo Chemical Industrial Company of Japan has recently developed a caprolactone-based (caprolactone - based) copolymer-based biodegradable plastics. So far, the company focus on the development of the agricultural covering film,[link widoczny dla zalogowanych], using the compounds as lactone polyesters (polycaprolactone) and aliphatic polyester blends. Allegedly, the R & D by the Competition Luo physical properties of new copolymers is much better than existing products, the company intends in the next few years, the construction of an industrial scale plant, currently under investigation and study its feasibility. Copolymers based on their own new product lactone ? (? a eaprolaetone) based, when it was made into films, its tensile strength and elongation is much higher than generic products, In addition, the copolymer product transparent film can be completed preparation, and the traditional film products, basic color is white. Coverage on the film as an agricultural experimental work has been made to the satisfactory results, its performance is better than generic products has also been affirmed. In the spring of 2003, large-scale promotion of new products, and gradually replace the existing products. Tokai Rubber Company developed a new high-performance damping materials, Tokai Rubber Industries has recently developed an automotive shock absorber rubber products used in the manufacture of new rubber material, the material damping is said to reduce the noise effect, can take car comfort more than 2O% increase. With this new material is based on morphology (morpholopy) theory and the company's exclusive technology, the implementation of several rubber compound of the results. Mainly to the high attenuation performance rubber (island phase) well distributed in the low dynamic spring constant of rubber (marine), the ratio by controlling the phase and shape of the island, to the past,[link widoczny dla zalogowanych], a variety of difficult to achieve unity of opposing function well in a kinds of materials to achieve the desired noise damping effect, the current domestic and foreign patent applications of the technology is. The material has been in the car for the trial, except for motor vehicles, railway vehicles can also be used for damping rubber and tape, hose and so on. Anti-vibration rubber for use as a rubber material,[link widoczny dla zalogowanych], its performance in the dynamic spring constant, driving the car has great influence the transmission of vibration, dynamic spring constant of the smaller,[link widoczny dla zalogowanych], the better shock absorption, and attenuation coefficient in the shock driving the car absorption (damping) has a great influence, the greater the coefficient, the better shock absorption. In the same material, show different characteristics of these two effects, one good effect, then the other party will badly, want to achieve the harmony and unity is very difficult, and the successful development of new materials to solve this conflict.
