insoluble sulphur. insoluble sulfur is an important rubber additive agent. it improves product quality, wearability and resistance to both fatigue and ageing. in addition to being universally recognized as the best vulcanizing agent, it is widely used in the manufacture of tire, rubber pipe, shoes, cable and wire insulating materials, latex.
is 90-65 (sulfur) - rubber chemical additive,isogran is 90-65 is a vulcanizing agent for all natural and synthetic rubber compounds in which sulphur bloom or infiltration of neighbouring layers of compound should be avoided. the use of insoluble sulphur isogran is 90-65 is therefore recommended for all applications that require laying-up, welding, or where good ply-adhesion is.
struktol® plastic additives for struktol ul prospector
- two basic types of sulfur are used for rubber compounding, i.e. ordinary ground sulfur called "soluble sulfur" because of its solubility in carbon disulphide (cs2), and the so-called "insoluble sulfur" which is insoluble in cs2. this characteristic of the sulfur types is.

india starts antidumping probe into insoluble sulphur imports from,insoluble sulphur, by definition, is a polymeric sulphur which is insoluble in carbon disulphide, and is generally used as a vulcanisation agent in some rubber application, said dgtr. the substance, it added, is “an important rubber additive agent”, which improves quality, wearability and resistance to fatigue and ageing.
- What is insoluble sulphur used for?
- Insoluble sulphur is mainly used as a vulcanising agent for rubber It allows for a more solid adhesion of the rubber, prevents the rubber from breaking apart and improves resistance to heat and tyre wear, and is therefore an essential raw material in tyre production.
- Why is insoluble sulfur a vulcanizing agent?
- Insoluble sulfur is important in the rubber industry as a vulcanizing agent since, when it is used, it can prevent rubber compounds from blooming during storage or during a production process without any adverse impact on the vulcanization process.
- Which polymers are subjected to sulfur vulcanization?
- The main polymers subjected to sulfur vulcanization are polyisoprene (natural rubber, NR), polybutadiene rubber (BR) and styrene-butadiene rubber (SBR), and ethylene propylene diene monomer rubber (EPDM rubber). All of these materials contain alkene groups adjacent to methylene groups.
- What is the least expensive approach to rubber compounding?
- Powders provide the least expensive approach to rubber compounding. Performance additives are not needed when they don’t bring value or provide clear benefits. However, as this white paper illustrated, the least expensive raw material doesn’t always translate to the lowest cost compound.
- What products do we offer to the rubber industry?
- Representing premier suppliers around the world, we offer the rubber industry the necessary products to get started, including coating, adhesive, sealant, and elastomer (CASE) technologies, chemical additives and fillers for manufacturing, and natural and sustainably sourced materials.
- What type of compound is used in rubber compounding?
- c) amorphous (insoluble in CS 2). In rubber compounding practice, forms a) and c) are used. Both types may be used in their natural form or may be coated. The coating can be oil, or MgCO 3, or silica, or some other material that aids dispersion in the rubber compound. Sulfur is available in varying degrees of fineness.
