The difference between pc material and tpu material: different shapes, different components, different characteristics, different uses
One, different shapes
pc material
pc material is square
tpu material
tpu material oval
The different components
pc material
The difference in the material is that it is a strong thermoplastic resin, its name comes from its internal CO3 group. /p>
pc material name for polycarbonate, the composition is a strong thermoplastic resin, its name comes from its internal CO3 group. It can be synthesized from bisphenol A and carbon oxychloride (COCl2). The more commonly used method is now the melt ester exchange method (bisphenol A and diphenyl carbonate are synthesized by ester exchange and polycondensation reactions).
tpu material
tpu material name for thermoplastic polyurethane elastomer, the composition is by diphenyl methane diisocyanate (MDI) or toluene diisocyanate (TDI) and other diisocyanate molecules and macromolecules of polyols, low molecular polyols (chain expander) **** with the reaction polymerization of polymer materials.
Three, different characteristics
pc material characteristics
1, with high strength and coefficient of elasticity, high impact strength, wide range of temperatures;
2, a high degree of transparency and freedom of coloring;
3, low shrinkage rate of molding, dimensional stability is good;
4, fatigue resistance is good;
5, Good weather resistance;
6, excellent electrical characteristics;
TPU material characteristics
1, wide range of hardness: by changing the ratio of TPU reaction components, you can get different hardness of the product, and with the increase in hardness, the product still maintains good elasticity and wear resistance.
2, high mechanical strength: TPU products have outstanding load-bearing capacity, impact resistance and shock absorption.
3, TPU cold resistance is outstanding: TPU's glass transition temperature is relatively low, at -35 degrees Celsius still maintains good elasticity, flexibility and other physical properties.
4, good processing performance: TPU can be processed using common thermoplastic materials processing methods, such as injection molding, extrusion, calendering and so on. At the same time, TPU and some polymer materials **** with the processing of polymer alloys can be obtained with complementary properties.
5, oil, water and mold resistance.
6, good recyclability.
Four, different uses
pc material
Use: optical lighting, electronic appliances, mechanical equipment, medical equipment, etc.
tpu material
Use: daily necessities, sporting goods, decorative materials, etc.
