Silicone hose as a common industrial tubing, the production of raw materials is critical. In this article, we will analyze the raw materials of silicone hose production, to provide you with a comprehensive understanding and reference.

Silicone raw materials

Silicone rubber, the core material in silicone hoses, determines their performance through its composition. A polymer of silicon dioxide, it offers high temperature resistance, corrosion resistance, aging resistance, and elasticity, making it ideal for industrial applications, especially high-heat environments and those requiring corrosion resistance.


In the production process of silicone hose, some auxiliary materials are usually added to improve the performance and processing of silicone hose. These additives include but not limited to:

  1. Fillers: used to improve the physical properties of silica gel, enhance the hardness and abrasion resistance of silica gel.
  2. Crosslinking agent: used to promote the crosslinking reaction of silica gel molecules, to enhance the elasticity and heat resistance of silica gel.
  3. Stabilizers: used to improve the stability of silica gel and prevent it from decomposing or deteriorating during processing and use.
    The selection and proportion of these additives have an important influence on the performance and quality of silica gel hose.

Silicone Hose Production process

The production process of silicone hose usually includes the following steps:
Raw material preparation: the silicone raw materials and various additives in accordance with a certain formula ready for subsequent processing.
Mixing and molding: the prepared raw materials into the mixer for mixing, so that it is evenly mixed, and add crosslinking agents and other auxiliaries.
Extrusion molding: Send the mixed silicone material into the extruder for extrusion molding to form a continuous silicone hose.
Curing: The molded silicone rubber undergoes a curing process to induce cross-linking and convert it into a solid elastomer.
Post-treatment: The extruded silicone hose is subjected to post-treatment, such as annealing and vulcanization, to improve its performance and quality.
Inspection and Packaging: Quality inspection of the produced silicone hose, packaging and storage after qualified, pending factory sales or use.

Quality control

In the production process of silicone hose, strict quality control is the key to ensure product quality. This includes strict control of raw materials, fine control of the production process, comprehensive inspection of finished products and other links. Only by ensuring that each link meets the standard requirements, can we produce high-quality silicone hose to meet the needs of users.


Analyzing silicone hose raw material production helps understand its manufacturing process and key factors. Choosing quality silicone, optimizing additives, controlling production, and rigorous inspection ensure high-quality hoses.
