The main purpose of adding additives to plastics is to improve processing performance, increase efficiency and reduce costs. Plastic additives occupies a small proportion in plastic materials, but they have a great impact on the quality of plastic products. Different types of plastics require different types and amounts of additives due

【general introduction】 The drying filter used in the paper industry is made from PET monofilament. It is used in high temperature and humid environments for a long time. The PET filter is prone to hydrolysis reaction. Adding HyMax® hydrolysis stabilizer to the PET monofilament can extend the service life. It can

The main material used by a customer in the post-processing stage of the product is two-component waterborne polyurethane, and isocyanate is used as the curing agent. However, during the specific production process, the customer found that if the formulated water-based polyurethane is not used up in time, the gel will

A clothing customer’s orders are mainly from the European Union. The EU has been strict in chemical control. Many batches of clothing exported by the customer were found containing chemical substances banned by the EU. The loss of direct goods and the sharp decline in subsequent orders have caused huge

Auxiliary additives for biodegradable plastics are an important subsidiary of biodegradable plastics. In recent years, the production and demand of biodegradable plastics have developed rapidly, and the auxiliary industry is also facing opportunities and challenges. This article counts the essential additives for several major types of biodegradable plastics. a) Crystalline

 What is polycarbodiimide crosslinking agent? 1. polycarbodiimide crosslinking agent Polycarbodiimide is a new type of crosslinking agent in the coating industry. Because it can be emulsified in water by introducing hydrophilic groups, it can be used for crosslinking of water-dispersed coating agents. When polycarbodiimide crosslinking agent is used, the coating

Overview of carbodiimide Polyurethane materials have a wide range of uses. Polyurethane elastomer is an important part of polyurethane materials. The products obtained by the reaction of polyester polyols and isocyanates have been recognized by the market for their excellent impact resistance and abrasion resistance. application of carbodiimide Carbodiimide’s application include

Carbodiimide, contains N=C=N functional groups, and is a commonly used dehydrating agent. It is generally prepared by thiourea losing hydrogen sulfide or urea losing water, and hydrolyzed to obtain urea derivatives. Mainly used to activate carboxyl groups to promote the formation of amides and esters. Basic Information of carbodiimide English

Concept and degradation mechanism of biological degradable polymer materials The biodegradable polymer material refers to a polymer material that degrades under the action of the microbes or their secretions under certain times and certain conditions. The mechanism of biodegradability roughly the following three ways: Biological cell growth causes mechanical damage of
