Q:How to distinguish between rubber and polyvinyl chloride?

The molecular chain of rubber can be crosslinked, and the crosslinked rubber can recover quickly when it is deformed by external force, and has good physical and mechanical properties and chemical stability. Rubber is the basic raw material of rubber industry. It is widely used in making tyres, rubber hoses, tapes, cables and other kinds of rubber products.

Q:How can I make rubber products brighter?

Special release agent for rubber products, release agent.Mold release agent is an interface coating used on two surfaces that are easy to adhere to each other. It can make the surface of the material easy to break off, smooth and clean. Mold release agent is used in various molding processes, such as glass fiber reinforced plastics, metal die casting, polyurethane foam and elastomer, injection molding thermoplastic, vacuum foaming sheet and extrusion section. In molding, sometimes other plastics, such as plasticizers, leak to the interface, and then a surface remover is needed to remove it.

Q:Is carbon black and conductive carbon black used in rubber?

Carbon black is divided into two major categories according to its use and usage:1. Rubber carbon black2, non rubber carbon black (or special carbon black, dedicated carbon black), including pigment carbon black, conductive carbon black, carbon black used for plastics, and a variety of special carbon black and so onMay refer to: Li Bingyan edited the "carbon black production and Application Manual."

Q:High strength rubber repairing agent

The operation time, generally require the hole position Polish cleaning after the rubber putty filled in the damaged parts, and then use the scraper scraping smooth, repair parts and guarantee the smoothness can be part of the belt.

Q:Are there formaldehyde in rubber products, too?

Outstanding performance: headache, dizziness, fatigue, nausea, vomiting, chest tightness, eye pain, sore throat, poor appetite, palpitations, insomnia, weight loss, memory loss and autonomic nerve disorder; long-term inhalation of pregnant women may result in fetal deformity, even death, men's long-term inhalation can cause male sperm deformity and death.

Q:What kind of rubber products are expensive?

The size and size of rubber products determine the amount of glue used, which is a matter of cost;

Q:How do rubber undergo vulcanization?

In the process of hot vulcanization, the general temperature is 10 degrees higher, and the curing time is shortened by about half. Rubber is a bad conductor of heat, which can easily cause uneven vulcanization.

Q:Is rubber flame retardant?

Rubber itself is flammable, in the production process can be filled with some flame retardant material, it can reduce its flammability, but at the same time reduce its inherent good performance, such as abrasion resistance, elasticity, etc..

Q:What is food grade natural rubber?

Standard rubber, natural rubber latex concentrate only and solid and liquid substances is concentrated latex by high-speed centrifuge after processing, required special barrel plus fresh, dry rubber content is 60%; the standard is a standard solid rubber rubber good solidification, machining, drying, packaging, which according to the impurity content to several levels and it has international standards, countries also have the corresponding standard.

Q:What kind of material does the shockproof rubber cushion usually choose? What's the hardness?

Recommend the use of EPDM, its good elasticity, although lower than natural rubber, isoprene rubber and butadiene rubber but its resistance to aging, corrosion resistance, chemical resistance, resistance to high pressure steam performance advantage, so compared to choose EPDM.Shock absorbing rubber used to be the only adhesive for NR in the past. In recent years, in order to meet the requirements of increasing heat resistance and oil resistance of automobiles, IIR, EPDM, NBR and CR have also begun to be used, and even microcellular PU elastomers and TPE thermoplastic elastomers have appeared. In addition, according to automotive requirements, in order to achieve lightweight targets, plastics have begun to replace metal, so-called rubber and plastic shock absorption rubber products.
