Hangzhou Xiaoshan Zhengda Textile Co., Ltd. is an enterprise specializing in the research, development, production and trade of Oxford cloth and apparel fabrics. Our products include Oxford cloth, jacquard cloth, etc., and its applications range from clothing to luggage, luggage and other outdoor sports goods. We also have sales of pu coated fabric.

PA is an acrylic coating material that can be dissolved by TOL\MEK\DMF, while pu coated fabric is a polyurethane coating material that can be dissolved by MEK\DMF but TOL cannot be dissolved. In addition, PA is sticky and can be glued with rubber. The pu coated fabric is smoother and softer than the hands.

pa is polyacrylate,

characteristic:

1. The crystalline material has a higher melting point and a narrow melting temperature range and poor thermal stability. The material temperature exceeds 300 degrees and the residence time exceeds 30 minutes. It is easy to absorb moisture, needs to be dried, and the water content should not exceed 0.3%.

2. Good fluidity and easy to overflow. It is advisable to use a self-locking nozzle and it should be heated.

3. The molding shrinkage range and shrinkage rate are large, the directionality is obvious, and shrinkage and deformation are easy to occur.

The pu coated fabric is polyurethane,

characteristic:

1. Good wear resistance

Polyurethane elastomer has excellent wear resistance

2. Wide range of hardness

The hardness of polyurethane elastomer is about Shao a10-d80, while the hardness of ordinary rubber is generally in Shao'S a60-100. It is worth noting that the polyurethane elastomer can have an elongation of 400-800% within such a hardness range. While the elongation of natural rubber is 550, the highest hardness is Shore a70

3. High strength and high elongation

4. Excellent oil resistance

The durability of polyurethane elasticity is better than that of cyanide-butadiene rubber. The weathering resistance is better than that of natural rubber and other synthetic rubbers. In terms of resistance to hydrolysis, acid and alkali solution corrosion, polyether pur is better than polyester pur.
