Basic Information

Polyber 55(O) is a special grade of NBR / PVC Polyblends with the polymer ratio of 50-50. It primarily consists of medium ACN Acrylonitrile Butadiene Rubber & Poly Vinyl Chloride pretreated Resin. This grade imparts high Ozone, Oil and Abrasion resistance. It can be easily blended with Nitrile Rubber to change the ratio as per need. 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 Polyber55(O) is very easy on conventional as well as modern rubber processing/compounding machines and also on plastic extruders. 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.It also holds out in high temperatures.

Recommendations

The plasticizers recommended are DOP, DOA, DOS, DBP, DINP other aromatic Plasticizers. Secondary Plasticizers such as CPW can also be used but only under guidance of a rubber technician. The mixing mill should be warm for best results.

Applications

Rubber Floorings, Rubber mats, Industrial Hoses, Hydraulic Hoses, Automotive Hoses, Auto parts, Extruded Rubber Parts, products which need smooth glossy finish etc.
