Silicone composite sealing strip

Silicone composite sealing strip is a sealing material made of silicone and other materials. Silicone material has good high temperature resistance, low temperature resistance and weather resistance, while the addition of other materials can enhance the strength, wear resistance or specific sealing characteristics of the sealing strip. Silicone composite sealing strip is widely used in sealing and sound insulation of various doors and windows, pipelines, equipment and machinery.

  • Quality control:

Quality control of silicone 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 heat resistance, weather resistance and wear resistance, as well as stable sealing effect.

  • Applicable scenarios:

Silicone composite sealing strips are suitable for sealing and sound insulation in various doors and windows, pipes, equipment and machinery. Due to the characteristics of its composite materials, different material combinations can be selected according to different application scenarios to achieve the best sealing effect. Common application scenarios include indoor and outdoor doors and windows, high temperature and high pressure equipment, chemical pipelines, etc.

  • Installation method:

1. Clean the installation surface: Make sure the installation surface 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 installation notch or fit the sealing surface to ensure that the sealing strip fits tightly with the surface.

  • Notes:

1. During installation, ensure that the sealing strip fits tightly to avoid gaps to ensure a good sealing effect.

2. The length of the sealing strip should match the length of the installation surface to avoid poor sealing effect due to excessive length or shortness.

3. Check the use status of the sealing strip regularly. If aging, damage or hardening 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., providing good sealing and sound insulation effects.

  • FAQ:

1. What is the heat-resistant temperature of silicone composite sealing strips?

- Answer: Silicone composite sealing strips usually have good heat resistance and can be used for a long time in high temperature environment. The heat-resistant temperature can generally reach more than 200°C. The specific heat-resistant temperature depends on factors such as material combination and thickness.

2. Will the installation of the sealing strip affect the normal opening and closing of doors and windows?

- Answer: A properly installed sealing strip will not affect the normal opening and closing of doors and windows, but it is necessary to ensure that the sealing strip fits tightly with the door and window frame to avoid gaps that affect the sealing effect.

3. How to replace the sealing strip after aging or damage?

- Answer: When the sealing strip is aged, damaged or hardened, it should be replaced in time. The specific methods for replacing the sealing strip include removing the original sealing strip, cleaning the installation surface, measuring and cutting the new sealing strip, and pressing and installing the new sealing strip.

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.
