Die Cut EPDM Gasket

Product description

Many of the die-cutting materials we work with are already used in a variety of industries:

Fireproof EPDM rubber gaskets are specialized sealing components designed to meet stringent safety requirements in environments where fire risks are a concern. These gaskets are made from Ethylene Propylene Diene Monomer (EPDM) rubber, which has been engineered to possess fire - resistant properties. EPDM rubber, in its base form, already offers a host of favorable characteristics. It is highly flexible, allowing fireproof EPDM rubber gaskets to conform to different shapes and surfaces with ease. Whether sealing irregularly shaped machinery parts or complex joints, the gasket can adapt to ensure a tight fit.

The fire - resistant nature of these gaskets is achieved through a combination of factors. Specialized fire - retardant additives are incorporated into the EPDM rubber compound during the manufacturing process. These additives work by either releasing non - combustible gases when exposed to high temperatures, which dilutes the oxygen available for combustion, or by forming a protective char layer on the surface of the gasket. This char layer acts as a barrier, preventing the underlying rubber from further burning and slowing down the spread of fire.

In terms of chemical resistance, fireproof EPDM rubber gaskets inherit the excellent chemical resistance of regular EPDM rubber. They can resist a wide range of chemicals, including acids, alkalis, and many solvents. This makes them suitable for use in industrial settings where they may come into contact with potentially corrosive substances, while also maintaining their fire - resistant properties. Fireproof EPDM rubber gaskets offer a reliable and versatile solution for sealing applications in fire - prone environments. Their combination of fire resistance, flexibility, chemical resistance, and efficient manufacturing processes makes them an essential component in ensuring the safety and proper functioning of various structures and systems.

Producing Process

The manufacturing process of fireproof EPDM rubber gaskets starts with the careful selection of EPDM rubber and the precise formulation of the fire - retardant additives. The rubber compound is then mixed thoroughly to ensure an even distribution of the additives. After that, it can be shaped using methods such as compression molding or injection molding. In compression molding, the rubber is placed in a mold and subjected to heat and pressure to take on the desired shape. Injection molding involves injecting the molten rubber compound into a mold cavity. Post - molding, the gaskets may undergo additional treatments like trimming to achieve accurate dimensions and surface finishing to enhance their sealing performance.

Quality standard

Lanxin's insulation materials quality is 100% according to ISO9001 Standard. We seriously take care of the quality control from IQC to OQC, throughout each step of the production.

Inspection Execution

1. Sample Selection: If a sampling plan is in place, select the samples according to the plan. Ensure that the samples are representative of the entire batch or lot.

2. Measurement and Testing: Conduct the planned measurements, tests, and examinations on the samples. For example, measure the dimensions of a product using the selected measuring tools, perform functional tests to check if the product operates correctly, and visually inspect for any signs of damage, defects, or non - compliance.

3. Data Recording: Record all the inspection data accurately. This includes the measured values, the results of the tests, and any observations made during the inspection. Use a standardized format for recording to ensure consistency and ease of analysis.

4. Defect Identification: If any defects or non - conformities are found, clearly identify and document them. Classify the defects as critical, major, or minor based on their impact on the product's functionality, safety, or compliance with standards.

5. Follow - up (if necessary)

7. Rework and Re - inspection: If the product requires rework, ensure that the rework is carried out according to the approved procedures. After rework, conduct a re - inspection to verify that the defects have been corrected and the product now meets the acceptance criteria.

8. Corrective and Preventive Actions: If recurring defects or systemic issues are identified, initiate corrective and preventive actions. This could involve investigating the root cause of the problems, implementing process improvements, and providing additional training to the relevant personnel to prevent similar issues from occurring in the future.
