Molded high resilience is a kind of flexible foam with excellent properties, such as light weight, softness, high resilience and high hand comfort, etc. and is also widely used in automobiles, furniture and other industries related to daily life. However, some problems in the production process are becoming more and more concerned by producers.
When everyone is full of confidence that China's polyurethane industry has entered a stage of rapid development, we should pay more attention to the future development direction of polyurethane.
For some thermoset polyurethane wastes with a low degree of crosslinking, it has a certain thermosoftening plasticity between 100-200°C. Within this problem, heating and pressurization can be directly bonded together without the use of adhesives.
As we all know, polyurethane is very versatile. At the same time, the factories of polyurethane foam produce a large amount of offcuts, mold spills, and waste products every year, as well as polyurethane waste in various fields need to be disposed. The recycling and reuse of these waste can not only reduce environmental pollution, but also conserve resources.
With excellent performance, lower price, low-carbon environmental protection and many other advantages, composite frame has a very broad application prospect in the photovoltaic industry.

Polyurethane rigid foam is mostly closed-cell structure, with excellent characteristics of good thermal insulation effect, light weight, high specific strength and convenient construction. It also has the features of sound insulation, shockproof, electrical insulation, heat resistance, cold resistance, solvent resistance, etc., and is widely used in insulation system for building exterior walls.
DETDA ,chemical full name as Diethyltoluene diamine , is a steric aromatic diamines. It was first produced by Albemarle Company in the United States, and the brand is Ethacure 100 . DETDA 80 is the brand name of Lonza in Europe . Now China become the third largest manufacturer of DETDA .
we will share some common problems and solutions in the (Flat bubble assembly line):
Polyurethane flexible foam refers to a type of flexible polyurethane foam with a certain elasticity, and it is one of the largest polyurethane products. The main products include high resilience foam (HRF), splimp sponge, slow resilience foam, integral skin foam (ISF), and semi-rigid energy-absorbing foam.
