Apply "Sealing" According to Your Aptitude, Did You Choose the Right Sealing Strip?

In the door and window system, the performance of air tightness, water tightness, and heat insulation is closely related to the performance of the sealing strip. Inferior door and window sealing strip will seriously affect the overall performance and quality of doors and windows.

Nowadays, water leakage in doors and windows and air leakage in windows often occur in the market. What causes the ineffective of the sealing strip? Today I will summarize the following points for everyone:

Q1: Quality question
The quality of the sealing strip is usually directly linked to the manufacturer. There are many reasons for the quality of sealant products on the market, such as unstable quality of raw materials, uneven mixing of rubber materials, improper curing conditions (temperature, time, pressure, etc.), improper product storage, etc. The above problems are often related to product quality control in the production process. Therefore, selecting quality and quality inspection production companies is the key to correct selection of materials.

Q2： Material selection and design errors
Material selection and design errors of sealant strips are usually caused by designers' unfamiliarity with product materials and performance, such as inaccurate estimation of pressure on seals, incorrect estimation of force distribution on contact surfaces, and unreasonable groove design. Therefore, it is particularly important to examine the product development and design capabilities of the manufacturing company.

Q3： Improper installation and use
Even if the best sealing strip is installed and used improperly, the sealing performance of the entire product will fail. Therefore, in addition to selecting high-quality products, it is also necessary to understand the company's service level, such as on-site installation, commissioning, and after-sales technical service support.

As a rubber-based company, 3H has nearly 40 years of extensive experience in the development and manufacturing of sealant strips and a scientific quality management system. Foshan Meirun Rubber & Plastic Technology Development Co., Ltd., a subsidiary undertaking the headquarter adhesive strip business, has an independent office building, R&D center and production base.

The 3H sealing strip production base covers an area of about 130 acres and has 5 major production workshops including rubber molding, EPDM rubber extrusion, rubber compounding, PVC extrusion, and automatci sealing. The monthly capacity of EPDM rubber extrusion workshop is 900 tons, the monthly capacity of rubber compounding workshop is 1,000 tons, and the monthly capacity of PVC extrusion workshop is 200 tons. The rubber products produced are produced in accordance with the high standards of automotive products and are widely used in urban landmarks,construction and engineering projects at home and abroad.

In addition, 3H Meirun Rubber & Plastics Division has a mature and professional design and R&D team. In the product design stage, designers will comprehensively consider product use scenarios, performance requirements, ambient temperature and other factors, and use professional CAE software to analyze product design structure and force deformation behavior to optimize product structure and material design. Ensure the rationality of product design and avoid the ineffective of the sealing strip.

In addition to leading product development capabilities, 3H Meirun Rubber and Plastics Division also has an experienced technical team to provide customers with technical services such as on-site installation and commissioning. From the early stage of material selection, design and development, quality control, installation and commissioning, transportation and packaging, 3H has always maintained close contact with customers, and is committed to providing customers with more professional, efficient and quality technical service support and system solutions.
