Supplier of compounded rubber: Factors affecting the compounding process

2022-07-08

During the mixing process, the mixing temperature of natural rubber is generally controlled around 130℃, and the discharge temperature is usually controlled within the range of 130~145℃. If the temperature is too low, it often causes the rubber material to not clump under pressure; if the temperature is too high, it will soften the rubber, which is not conducive to the dispersion of filler quality. Therefore, the rubber mixing suppliers need to pay attention to the control and adjustment of cooling water or heating steam according to the process requirements, in order to control the temperature of the mixing chamber.

Supplier of compounded rubber: A brief introduction to compounded rubber

2022-06-23

The mixing rubber supplied by the supplier is a well-known high-performance rubber, especially known for its excellent resistance to high temperatures, ozone, weather, oxidation, mineral oils, fuel oils, hydraulic oils, aromatics, and many organic solvents and chemicals. The FKM system from the mixing rubber supplier is now available in blends such as normal (66% F), medium F (67-68.5% F), high F (70% F), improved low-temperature elasticity (64.5-67% F), and excellent additional chemical and solvent resistance (66% F).

Some knowledge points about polyurethane blended rubber, explained by the blended rubber manufacturer.

2022-04-25

Polyurethane blended rubber is a type of mixed polyurethane rubber (referred to as MPU) synthesized from polyether polyols and methylene diphenyl diisocyanate (MDI) with an unsaturated structure. The vulcanization system can choose between peroxides or sulfur. The processing technology and vulcanization molding processes and equipment are the same as those for general rubber; it is suitable for manufacturing rubber products with hardness ranging from Shore A 50 to 95.

The process and characteristics of compound rubber, as told by the compound rubber manufacturer.

2022-04-11

The manufacturer of mixing rubber believes that mixing is the process of using the mechanical force of a rubber internal mixer to evenly disperse various compounding agents in the rubber. The mixing process is to evenly disperse various compounding agents in the rubber, forming a medium of rubber or a mixture of rubber with some compatible components (compounding agents and other polymers) as the medium, and a multiphase colloidal dispersion system with incompatible compounding agents (such as powder fillers, zinc oxide, pigments, etc.) as the dispersed phase.

A one-minute explanation by the rubber compound supplier about what rubber compound is.

2022-04-02

The so-called compounded rubber refers to a type of unvulcanized rubber that has fluidity, in which the compounding agents are mixed in block, granule, or powder form. According to compounded rubber suppliers, the rubber material that is mixed with the compounding agents according to the formula using a rubber mixing machine is called compounded rubber. Compounded rubber suppliers indicate that compounded rubber is mainly used for automotive parts, front and rear main shaft oil seals, front and rear crankshaft oil seals, power steering pump seals, transmission pump seals, dust covers, power steering hoses, and 175-degree radiator hoses.

The UV adhesive manufacturer will introduce the curing time of UV glue and the reasons for whitening.

The UV adhesive manufacturer will introduce the curing time of UV glue and the reasons for whitening. Users should pay attention to taking protective measures to avoid discomfort and allergies caused by operators talking on the phone for long periods. It is recommended to maintain good air circulation in the workplace where UV glue is handled. If cost is not a concern, UV adhesive manufacturers can focus on the selection of raw materials to produce products with relatively low odor; however, it is very difficult to achieve a completely odorless product.

How are rubber rollers classified? Let's hear what the experts from the rubber roller manufacturers have to say!

Rubber rollers are quite common in industrial production and are suitable for processes such as coating, composite, and transportation. In the production of rubber roller bodies, different materials are used for the rubber layer produced by rubber manufacturers according to various production process requirements. Below, rubber rollers can be classified based on different rubber layer materials, including natural rubber, EPDM, neoprene, silicone rubber, and fluororubber.

What should be done if the mixed rubber is unqualified?

How should unqualified mixed rubber be handled? Does anyone know? Regarding how to deal with unqualified mixed rubber, we must first identify the reasons and then take targeted measures. (1) Supplement mixing For rubber materials with uneven hardness and relative density, due to uneven plasticity and dispersibility, supplementary mixing can be stopped. The method is as follows: the rubber material is averaged on the open mill, and those that pass the quick inspection can be mixed in at 50% with the same rubber material; those that do not pass should have the reasons further investigated and handled separately. (2) Add compound agent.

Do you know why the mixed rubber needs to be left to stand for a period of time?

Do you know why the mixed rubber needs to be parked for a period of time? The processing of rubber materials reduces the shrinkage of the rubber material. The main material of rubber composites is high-elasticity elastomers. They are stretched and pulled by mechanical force during the plasticization and mixing process; once these external forces disappear, there will be a strong elastic recovery (and shrinkage), which is an inherent characteristic of elastomer materials. However, shrinkage is not conducive to product molding. During parking, the shrinkage runs through the entire process. Although the shrinkage process is slow, the mixed rubber can be made into various sizes after parking, and the size is relatively easy to control.
