The fine Chemicals Research and Development Department of Shanxi Chemical Research Institute (Co., LTD.) adheres to the concept of "unique characteristics, innovation, excellence, pragmatism and truth", and conforms to the development trend of general plastics engineering, high performance engineering plastics and green plastics industry represented by bio-based and biodegradable plastics. Committed to the technical innovation of high-performance, specialized polymer additives, and actively develop and research series of special additives, constantly innovate, new products emerge in an endless stream, recently its special nucleating agent for engineering plastics — — Nucleating agents TMN-102 and TMN-22 broke through technical difficulties and successfully completed pilot industrialization.

TMN-102 special properties make it widely used in polyamide engineering plastics: in all kinds of injection grade polyamide has excellent nucleation and lubrication effect, can shorten the injection cycle by 25%; Applied to polyformaldehyde and polyolefin resin can neutralize the acidic substances in the resin, prevent the accelerated aging of the resin, compared with calcium stearate, TMN-102 as an acid absorber is unique in its extremely low volatility, even at high temperatures. TMN-102 has excellent thermal stability, low volatility and color stability, and can provide excellent nucleation effect and lubricating release effect without affecting the transparency and mechanical properties of polyamide, and will not cause polymer degradation.

TMN-22 is a special nucleating agent for a variety of polyamides, which is uniformly dispersed in polyamide resin, inducing polymer molecular chain rearrangement crystallization, to promote the crystallization rate of resin, improve the crystallinity and improve the purpose of product processing and application performance. TMN-22 in the injection molding processing has the following advantages: shorten the molding cycle, improve production efficiency; Improve demoulding; Improve the dimensional stability of the product, reduce the shrinkage after the product, prevent the product stress cracking; Improve mechanical properties (improve tensile strength and hardness), the above modification effects not only exist in the unreinforced nylon, in the reinforced nylon is also effective, especially suitable for glass fiber reinforced nylon.

In recent years, Shanxi Institute of Chemical Industry (limited company) has actively integrated into the Shanxi regional science and technology innovation system, committed to the innovation of coal-based polymers and their functional additives, established the coal-based polyolefin, coal-based engineering plastics and coal-based biodegradable plastics as the modification target of coal-based plastics and their functional additives research direction. The successful pilot test of TMN-102 and TMN-22 marks the smooth implementation of nylon nucleating agent project and has made a major breakthrough. In order to realize the high performance of nylon 6 and other general engineering plastics, expand its application range and improve its added value is of great significance.
