EPDM three-composite sealing strip

EPDM tri-composite sealing strip is a sealing material made of three different materials, usually including EPDM rubber (EPDM) and two other materials, such as polyurethane, polypropylene, etc. This sealing strip combines the advantages of three materials, with the good elasticity and weather resistance of EPDM rubber and the characteristics of the other two materials, thus providing a more diverse sealing solution.

  • Quality control:

The quality control of EPDM tri-composite sealing strips usually includes raw material inspection, production process control, finished product inspection and performance testing. Through strict quality control, it is ensured that the sealing strips have good elasticity, weather resistance and wear resistance, as well as stable sealing effect.

  • Applicable scenarios:

EPDM tri-composite sealing strips are suitable for sealing and sound insulation in various doors and windows, vehicles, mechanical equipment and pipelines. Due to the diversity of its material combination, it can adapt to the use requirements under different environmental conditions, such as indoor and outdoor doors and windows, high temperature and high pressure environment, chemical equipment sealing, etc.

  • Installation method:

1. Clean the installation surface: Make sure that the surface of the door and window frame notch is clean, dry, free of oil and dust.

2. Measuring and cutting: Measure and cut the sealing strip according to actual needs to ensure the appropriate length.

3. Press-in installation: Press the sealing strip into the notch of the door and window frame to ensure that the sealing strip fits tightly with the notch.

  • Notes:

1. During installation, ensure that the sealing strip fits tightly with the notch of the door and window frame to avoid gaps to ensure good sealing effect.

2. The length of the sealing strip should match the length of the notch of the door and window frame to avoid poor sealing effect due to excessive length or shortness.

3. Check the use status of the sealing strip regularly. If aging, hardening or damage is found, it should be replaced in time to maintain the sealing effect.

  • Application scenarios:

Home doors and windows: suitable for wooden doors, aluminum alloy doors and windows, plastic steel doors and windows, etc., provide good sealing and sound insulation effects, and keep the indoor environment comfortable.

Commercial buildings: suitable for door and window sealing in shops, office buildings, hotels and other places, provide sound insulation and thermal insulation effects, and improve the comfort of the indoor environment.

Industrial buildings: suitable for door and window sealing in factories, workshops and other places, provide wear-resistant, weather-resistant and durable sealing effects, and keep the indoor environment clean and quiet.

  • FAQ:

1. How is the weather resistance of the three-composite sealing strip?

- Answer: EPDM has good weather resistance and can be used for a long time in indoor and outdoor environments without aging or hardening. The weather resistance of the other two materials will also vary depending on the specific selected materials, and will usually be adjusted according to actual needs.

2. Is it complicated to install a three-composite sealing strip?

- A: The steps for installing a three-composite sealing strip are similar to those for installing an ordinary sealing strip, and are generally not too complicated. It is important to ensure that the sealing strip fits tightly with the installation notch to ensure a good sealing effect.

3. Is the price of a three-composite sealing strip higher than that of an ordinary sealing strip?

- A: Since the three-composite sealing strip is made of a combination of multiple different materials, the production cost may be slightly higher than that of an ordinary sealing strip. However, it provides more diverse performance and application options, which can meet a wider range of sealing needs, so in some specific application scenarios, its cost-effectiveness may be higher.

4. How is the three-composite sealing strip different from an ordinary sealing strip?

- A: The three-composite sealing strip is made of three different materials and has more

Sealing Strip Production Process

Raw Material Procurement
The company rigorously selects high-quality suppliers to procure rubber, plastics, and various additives that meet national and international standards, ensuring material quality.
Raw Material Inspection
Advanced equipment and a professional team are employed to comprehensively inspect raw materials, including their physical and chemical properties, ensuring they meet production requirements. Only materials that pass inspection proceed to the production phase.
Compounding and Mixing
Accurate compounding and mixing are conducted according to product formulation ratios. High-efficiency mixing machines ensure thorough blending of raw materials to achieve uniform consistency. The mixed materials undergo a maturation period to ensure material stability.
Extrusion Molding
Maturation-treated mixed materials enter the extrusion molding process. Different extruders and molds are used based on product shapes and specifications. Stringent control of parameters such as temperature, pressure, and speed ensures products meet design requirements in terms of size and appearance.
Vulcanization and Cooling
Products after extrusion molding undergo vulcanization to enhance their physical properties and durability. Vulcanization occurs under high temperature and pressure conditions using vulcanization machines to ensure uniform curing. Post-vulcanization, products undergo cooling to further stabilize performance.
Cutting and Processing
Cooled products enter the cutting and processing stage. Precision cutting and further processing such as edge trimming and hole punching are performed according to specific product requirements. During processing, strict control of dimensions and accuracy ensures products meet design specifications.
Surface Treatment
Processed products undergo surface treatment as required, such as spraying, impregnation, or bonding. Surface treatment enhances product appearance and improves properties such as corrosion resistance, waterproofing, and wear resistance.
Final Inspection
All finished products undergo rigorous final inspection. The company utilizes advanced testing equipment and a professional quality inspection team to comprehensively test dimensions, physical properties, chemical properties, etc. Only products that pass inspection are packaged and ready for shipment; non-conforming products are reworked or scrapped.
Packaging and Storage
Inspected and approved products proceed to packaging. Suitable packaging materials and methods are selected based on product characteristics and customer requirements to ensure products remain undamaged during transportation and storage. After packaging, products are stored in the warehouse awaiting shipment.
