Basic Information
Polyber – 73(J) is a special polyblend with specialty plasticizers for low Hardness and less viscous grade. It primarily consists of medium ACN Acrylonitrile Butadiene Rubber & Poly Vinyl Chloride Resin in the ratio of 70:30 and a greater dose of Plasticizer. It can be provided in both forms i.e. sheets and granules. It is available in 25 KGs HDPE paper bags packing for better handling.
Processing Characteristics
The Processing of Polyber 73(J) is very easy on conventional as well as modern rubber processing/compounding machines. It has a very efficient compounding method which further saves the cost, labor and time.It absorbs Filler and Plasticizer quickly which reduces the compounding time.
Recommendations
The plasticizers recommended are DOP, DOA, DOS, DBP, DINP other aromatic Plasticizers. Secondary Plasticizers such as CPW are not recommended for this grade. The mixing mill should be warm for best results.
Applications
Sponge products like Footwear, sports goods, Insulation sheets etc. and printing rubber rollers.
