Optical Brightener OB-1 For PET And RPET Fiber


PET or RPET, Polyethylene terephthalate, commonly known as polyester resin, is the most important variety of thermoplastic polyester. As a thermoplastic polyester, PET and PBT together become one of the five engineering plastics.

PET is used primarily in chemical fibers, synthetic fibers, and man made fiber, as well as in films and engineering plastics. PET has good optical properties and weather resistance, amorphous PET has good optical transparency. PET bottles are widely used because of their high strength, good transparency, non-toxic, anti-permeability, light weight, high production efficiency and excellent wear resistance.RPET as known as PET waste raw materials, also known as Coke bottle green material,is a kind of renewable and environment-friendly material. By using recycled plastic bottles, such as from plastic bottles to plastic bottles, 100% of the recycled materials can be recycled into RPET fibers, effectively reducing waste, protecting the Earth’s environment.

Because the RPET material has been used once, due to oxidation, sunlight, abrasion, dirt and other reasons, in addition to cleaning, in order to increase the added value of the RPET plastic waste material in the plastic recycling process, improve the whiteness and brightness of RPET fiber, it is necessary to add optical brightener OB-1 for plastic into the recycled raw materials in the plastic recycling enterprises.Jinan Ogilvy Chemical Co Ltd ,professional China Manufacturers in optical brightener, pigment,provide professional products whitening program for plastic recycling, plastic bottle recycling and plastic recycling processing.
