Peptizer For Natural Rubber

A peptizing agent for natural rubber and synthetic butadiene styrene rubber comprising a blend of a a mixture of an iron free peptizer and a zinc salt of mixed fatty acids and b an iron phthalocyanine.

Peptizer for natural rubber.

The main contents were as follows firstly the effects of the dosage of peptizer dbd temperature of mastication rotor speed and. They can also be used as an effective physical peptizer for the mastication of natural rubber to improve processability in mixing extrusion and molding. The peptizer can improve the plasticating effect of the rubber compound and shorten the mastication time thereby achieving the purpose of improving the production efficiency. To validate to method and formulation the experiment is repeated three times to find out the type of peptizer that provide the highest compatibility to masticate natural rubber.

Rubber elastic substance obtained from the exudations of certain tropical plants natural rubber or derived from petroleum and natural gas synthetic rubber. Mastication is an essential process in processing of natural rubber while using peptizer can reduce the viscosity of nr quickly. More than half of all rubber produced goes into automobile tires. Because of its elasticity resilience and toughness rubber is the basic constituent of the tires used in automotive vehicles aircraft and bicycles.

They can partly or totally replace conventional activators based on fatty acids stearic acid zinc stearate and zinc 2 ethylhexanoate and impart excellent reversion resistance. As a professional china peptizer manufacturer and suppliers we mainly supply peptizer with high quality and the best price. Properties typical values appearance beige pastilles ash content max 21 5 dropping point c 85 5 95 5 specific gravity 1 15 physiological behavior refer to safety data sheet. Recently the effect of peptizer in the mastication process of natural rubber butadiene rubber has been investigated by using vestenamer aktiplast 8 and rhenosin 145.

Akrochem peptizer 66 by akrochem is an activated 2 2 dibenzamido diphenyldisulfide dbdd absorbed on a clay carrier. It can be used as a processing aid viscosity reducer for natural and synthetic. A peptizing composition for natural rubber and synthetic butadiene styrene rubber comprising a from about 97 to about 99 by weight based on the weight of said composition of a mixture of 1 an iron free peptizer selected from the group consisting of a organic mercaptans b organic disulfides c zinc salts of organic mercaptans and d mixtures thereof and 2 the. The rest goes.

This paper studied the effect of environment friendlychemical and physical peptizers on mastication and properties of natural rubber.
