Rigid polyurethane foam has better flame retardancy than natural wood. Compared to glass fiber materials、 they have higher strength and better toughness p>
Rigid polyurethane foam has dense and tough skin、 sound insulation and waterproof、 low thermal conductivity、 convenient construction、 molding process identification、 high production efficiency and many other characteristics、 so it is widely used in the construction industry、 flame retardant insulation products、 refrigerator ice insulation、 thermal insulation materials、 structural weighing materials and other fields p>
Testing demand for rigid polyurethane foam
1. New product research and development needs to master the relevant process and data through testing
2. Quality measurement、 factory testing and type testing of rigid polyurethane foam products
3. Government approval、 and product listing requires a qualified test report to pass the government's filing and approval
4. Competitive product analysis、 through testing the performance and indicators of competitive products、 to learn from each other
5 Purchase decision: when purchasing products on a large scale、 the purchaser needs to confirm the quality
