Rubber mixing is a key link in the production of rubber products, covering steps such as uniform dispersion of raw materials, plasticization, mixing and maturation. During the mixing process, the storage and handling of rubber are crucial to the performance, processing performance and production efficiency of the final product. Among them, whether to use a release agent is a key factor. Powder Release Agent is a mixture of grayish white to light yellow powdered fine inorganic fillers and surfactants. It is a non-toxic, high-viscosity rubber release agent. So what are the effects of using powdered release agents on rubber?
1. Impact on the storage stability of rubber：
Rubbers using release agents are not easy to stick together during storage, especially in high temperature and high humidity environments, which prevents adhesion caused by partial flow of rubber molecular segments. Especially when using automated storage, long-term stacking or storage in roll form, release agents can effectively prevent deformation and adhesion of rubber.
2. Prevent oxidation, moisture absorption and pollution：
Some release agents (such as coating release agents containing antioxidant ingredients) can form a protective layer on the surface of the rubber, slow down oxidation, and improve the storage stability of the rubber. Powder Release Agent can reduce the adsorption of moisture in the air and prevent the rubber from being separated or denatured due to moisture absorption.
3. Improve the uniformity of the rubber：
The presence of Powder Release Agent helps prevent the rubber from agglomerating, making the shear force more uniform during subsequent processing and avoiding uneven plasticity caused by excessive shearing of local rubber during mixing.
4. Improve the fluidity of the mixed rubber：
During the internal or open mixing process, overly sticky rubber may affect the mixing uniformity. Using Powder Release Agent can reduce the friction coefficient of the rubber, help the rubber to be evenly distributed in the mixer, and improve the dispersion efficiency of fillers and additives.
We are a high-tech enterprise focusing on the research and development and production of environmentally friendly release agents and rubber additives. If you are also troubled by the stickiness between films, you can choose our powdered film release agent 1210, which can be seamlessly combined with rubber in the subsequent mixing and vulcanization stages to prevent the adhesion of unvulcanized rubber and will not have any adverse effects on its physical and chemical properties.
