Q:When rubber products are hardened, what methods soften?

The rubber is softened by soaking in the solvent, but it will damage the original physical and chemical properties of rubber!

Q:Is mixed silicone rubber dangerous?

Mixed silicone rubber silicone rubber is the synthesis of silicone rubber crosslinking agent + + + + auxiliary catalyst filler in the double roller mixer or a sealed kneading machine.

Q:Classification of other rubber sheets of wear-resistant rubber plates

RIT flat wear-resistant plywoodNon slip and relatively ordinary wear, usually used in less tension fabric, nylon belt, roller wrap, or ordinary environment of the drum wrapped plastic processing.RIT type wear resistant rubber plateThe surface of the rubber plate is of a rhombus shape, which has a strong anti slip and abrasion resistance. It is usually used in the fabric belt and middle and high strength steel belt and roller package processing. It is the most frequently used roller wrapped rubber sheet at present. Especially 10mm and 12mm thick rhombus rubber sheet.

Q:Can PVC blend with rubber?

PVC can be well compatible with NBR and difficult to use with other glue.

Q:What kinds of rubber are edible grade safety rubber?

1, natural rubber: often used in the manufacture of condoms, pressure cooker sealing ring and so on;2 butyl rubber: as a result of good sealing performance, often used as infusion bottles and oral liquid bottle rubber stopper;3. Food grade silica gel: high pressure cooker with long life cycle.

Q:How do rubber undergo vulcanization?

Rubber vulcanization is a chemical reaction process, before vulcanization rubber is present in a linear molecular form, is the linear sulfide molecules through some other substances (such as sulfur and peroxide) connected together to form a three-dimensional network structure. Sulfur must not be used with sulfur material, as long as the rubber linear molecules can be linked together to form a body shape on the lineEach rubber formulation has an optimum curing temperature, which increases the speed of vulcanization within a certain range, but the performance of the product decreases

Q:Is polyurethane and polyurethane rubber one thing?

Polyurethane is a very special polymer, it is composed of hard and soft segments, the hard part of Tg is very low, with plastic characteristics, soft section of Tg is higher than room temperature, a lot of rubber characteristics. In the process of synthesis of polyurethane, by controlling polymerization, the proportion of hard segment and soft segment of polymer can be adjusted, so that polyurethane can be expressed as plastic or rubber.Rubber shoes, excluding plastic shoes, should not be included in general sense. Common sense says in rubber overshoes, it is the waterproof shoe that rains commonly, army shoe, plastic shoe has slipper commonly.

Q:What are the application fields of waste tire rubber powder?

Waste tire rubber powder from 900 to 1200 waste tire as the main raw material, the production method of low temperature refrigeration by air turbine (0.425mm) 40 mesh to 200 mesh (0.0750mm) crumb rubber with high fineness, tensile strength, the proportion of small, good liquidity.

Q:Is rubber flame retardant?

Mainly to see the use of related products, for example, the glass door rubber strip is flame retardant, and the vehicle's internal and external tires are not flame retardant.

Q:What is rubber damping material?

A general term for polymeric materials with sound absorption, heat insulation, shock proof and other functions. Materials with larger internal friction peaks, such as polyacrylate, polyurethane, epoxy resin, butyl rubber and nitrile rubber, are often used at the service temperature and frequency.
