What is EPDM 70?

EPDM 70, commonly known as Ethylene Propylene Diene Monomer rubber with a hardness of 70 Shore A, is a type of synthetic rubber that is widely used in various industries due to its exceptional properties. It is known for its superior resistance to heat, ozone, and weather conditions, making it an ideal choice for outdoor applications. Additionally, EPDM70 boasts excellent resistance to water, steam, and certain chemicals, further expanding its range of applications.

One of the primary benefits of using EPDM70 is its ability to maintain its flexibility and elasticity even under extreme temperature variations. This makes it a preferred choice for sealing applications, especially in automotive and construction industries. From window and door seals to roofing membranes, EPDM70 has proven its worth time and again.

At Suzhou Baoshida Rubber, we understand the importance of quality and consistency when it comes to EPDM70 products. With years of experience in the rubber industry, we offer a wide range of EPDM70 products tailored to meet the specific needs of our clients.

The Production Process of EPDM 70

Raw Materials and Their Sources

The foundation of high-quality EPDM70 lies in the selection of premium raw materials. Ethylene, propylene, and a diene comonomer are the primary ingredients used in the production of EPDM70. These materials are sourced from reputable suppliers, ensuring that the resulting rubber meets the highest standards of quality and performance.

Step-by-Step Manufacturing Process

  1. Polymerization: The raw materials undergo a polymerization process, where they are combined under controlled conditions to form the EPDM rubber.
  2. Compounding: Various additives, including fillers, accelerators, and curing agents, are mixed with the EPDM rubber to enhance its properties and ensure optimal performance.
  3. Molding: The compounded rubber is then molded into the desired shape, be it sheets, seals, or any other product.
  4. Curing: The molded rubber is subjected to heat, allowing it to cure and attain its final properties. This step is crucial as it determines the rubber’s durability, elasticity, and resistance to various factors.

Quality Control Measures and Standards

At Suzhou Baoshida Rubber, quality is paramount. Every batch of EPDM70 undergoes rigorous testing to ensure it meets the set standards. From tensile strength tests to aging resistance evaluations, each aspect of the rubber is scrutinized. This meticulous approach ensures that every product that leaves our facility stands up to the reputation we’ve built over the years.
