The sealing strip is an indispensable and important component on doors and windows. The physical properties of the system doors and windows: air tightness, water tightness, sound insulation, etc., all depend on the performance of the sealing strip. What is a sealing strip, Baydee Upvc Profiles take you to understand:
Sealing strips are rubber strips used for product sealing, mainly used in automobiles, machinery, building doors and windows and other fields.
The sealing strips used in automobiles are mainly: EPDM rubber with good elasticity, compression deformation resistance, aging resistance, etc., which is compounded by rubber foam. Includes unique tongue buckle for durability and ease of installation.
Sealing strips for building doors and windows: refers to the components used in building doors and windows, such as glass and bead, glass and frame fan, frame and fan, fan and fan, etc. It can prevent the leakage or intrusion of internal and external media (rainwater, sand, air, etc.), so as to achieve sealing, sound insulation and heat insulation.
Sealing strips are also divided into several categories, let's take a look at the common ones:
Vulcanized rubber sealant
Generally, it is made of EPDM material. It has excellent comprehensive performance, outstanding ozone resistance, excellent weather resistance, good high temperature and low temperature resistance, outstanding chemical resistance, ability to withstand a variety of polar solutes, and low relative density.
Silicone rubber sealing strip
It has outstanding high and low temperature resistance, ozone resistance and weather resistance; it has good hydrophobicity and proper air permeability; it has excellent insulation properties; it can meet the hygienic level of food hygiene requirements, and can meet the requirements of various colors .
EPDM foam strip
It is a copolymer of ethylene, propylene and a small amount of non-conjugated diene. It is a kind of ethylene-propylene rubber. It is represented by EPDM. It has excellent ozone resistance, heat resistance and weather resistance. It is widely used in auto parts, waterproof materials, construction Windows and other fields.
Summary: At present, there are many manufacturers of door and window sealing strips, and the grades and quality of the products produced vary, resulting in a mixed market for sealing strips. Door and window sealing strip manufacturers not only provide product matching for doors and windows enterprises, but also get involved in the development and design process of doors and windows. Only in this way can the developed sealing strip products be more targeted, thereby extending the sustainability of the entire door and window industry. develop. Various composite sealing strips that have been subdivided for different uses are a direction for the development of EPDM strips in the future.
