Why the price of TPU soared in the beginning of 2021
Feb 25 , 2021
TPU is a polyurethane elastomer product. The raw materials of TPU such as polyol, MDI, BDO, adipic acid, ethylene glycol, etc. are all petroleum derivatives or by-products. In the beginning of 2021, the "energy crisis" hit global and domestic chemicals soared! A few days ago, many refineries closed! Oil prices, natural gas, and chemical products have skyrocketed! The biggest increase rea...

How to prevent and remedy the burrs(flash) in the TPU injection parts during injection process
May 10 , 2021
Burr is a common problem encountered in TPU injection products. A burr (also known as a “flash”) is an unwanted raised edge or small piece of TPU material left in a part after a injection manufacturing process. Burrs not only disfeature the appearance of plastic parts but also affect it’s properties. How to analysis and solve the burrs problem during TPU injection process. Burrs of a TPU...

TPU application in 3D printing and its advantages
May 17 , 2021
The types of plastics used in 3D printing plastics are becoming more abundant, and some products have achieved mass production. Plastic consumables account for 46.5% of 3D printing materials. PLA, ABS, nylon, and light-curing liquid resin consume relatively large amounts of the plastics consumables. In addition, thermoplastic elastomer (such as TPU) and engineering plastics ( For example, PA6, PC)...

Introduction of TPU full form and it’s 3 major material
Jun 09 , 2021
TPU is a block copolymer which is formed by the reaction and polymerization of diphenyl di-different properties (MDI), diisotropic compounds (TDI), macromolecular polyols and extender chains. It’s consisting of hard and hard segments. The soft segments are made of MDI, TDI and chain expander. The soft segments are made of MDI, TDI and macromolecular polyols. The soft segments are macromolecule dio...
