The suction plate is made of polypropylene. Polypropylene, referred to as PP, is a colorless, odorless, non-toxic, translucent solid substance. Polypropylene is a kind of excellent thermoplastic synthetic resin, it is a colorless translucent thermoplastic lightweight universal plastic. With chemical resistance, heat resistance, electrical insulation, high strength mechanical properties and good high wear-resisting processing properties, polypropylene has been widely developed and applied in many fields such as machinery, automobile, electronics and electrical appliances, construction, textile, packaging, agriculture, forestry, fishery and food industry since it came out. Hopetopway oil-absorbing pad is a kind of inert chemical polypropylene melt-blown process made from. Oil absorbent pad can effectively absorb liquid and retain it. The products absorbed by oil absorbent pads are wrapped in surface treated polypropylene fibers or non-woven fabrics. Oil-absorbing mat outer cloth is extremely tough and durable with strong absorbability. Oil absorbent pad can effectively absorb the leaking liquid and prevent the spread of the leakage.
