Application: PPR pipe extruding, pipe injection Feature: 1. Sanitary performance meet the Standard of GB/T 17219; 2. No color alteration till temperature up to 240; 3. Ensure master batch uniform distribution in the PPR processing, bottom out the effect of strengh and jointing, keep physics performance of the thing itself; 4. Good machining property, more smooth surface; 5. Better hiding power, solve the water quality changing problem due to light pollution in use. T series grey master batch are specially manufactured for water supplying plastic product, there have steady quality and machining property base on imported raw material. Application: PPR pipe extruding, pipe injection Feature: 1. Sanitary performance meet the Standard of GB/T 17219; 2. No color alteration till temperature up to 280, it resovles the two problems which color of products changing when PPR master batches in the big caliber product processing and color off joints changing when jointing in high temperature; 3. Ensure master batch uniform distribution in the PPR processing, bottom out the effect of strengh and jointing, keep physics performance of the thing itself; 4. Good machining property, more smooth surface; 5. Solve the problem of color changing after the product exposure to sunshine; 6. Solve the water quality changing problem due to light pollution in use.
