Advantages and disadvantages of HFC-245fa blowing agent in polyurethane spray foam

Advantages and disadvantages of HFC-245fa blowing agent in polyurethane spray foam

With the accelerated phase-out of HCFC-141b, the Center for Environmental Protection External Cooperation of the Ministry of Ecology and Environment recommends that the selection of HCFCs phase-out replacement technologies should be environmentally friendly, low-carbon, safe, and economical. This means no damage to the ozone layer; low global warming potential (GWP), good insulation performance, and high energy efficiency; production that meets safety standards; and a high cost-performance ratio, with raw material and production costs that are acceptable to the market.

The difference between traditional slow-rebound sponge and inflated slow-rebound sponge.

Slow rebound sponge, affectionately called memory foam, has made a significant impact in fields such as pillows, mattresses, and car seats due to its magical "slow recovery" characteristic, providing users with a unique zero-pressure experience.

Causes and solutions of slow curing of polyurethane rigid foam

Causes and solutions of slow curing of polyurethane rigid foam

Slow curing of polyurethane foam (gel reaction lag) is usually caused by imbalance in raw material formulation, improper process conditions or external environmental interference, which needs to be analyzed from the perspective of chemical reaction kinetics and thermodynamics. The following are the specific reasons and corresponding solutions:
