Silicone strip temperature resistance

by:Kenna     2021-05-20
Silicone strips are resistant to temperature. Since silicone sealing strips are mainly produced using silicone rubber materials, they have better sealing performance than other materials. They can also be used in some high-temperature environments and have excellent weather resistance. It can effectively resist the invasion of natural factors. Even if it is used for a long time, there will be no aging damage. Generally, the back of the silicone sealing strip is explained, so it can be effective without using any adhesive. It is bonded with other materials and has good sealing performance. No matter how long it is used in a high temperature environment, it will not fall off, so it has become the first choice for sealing materials. Introduction to electrical cabinet door self-adhesive sealing strips are made of three types of self-adhesive sealing strips with good elasticity and resistance to compression deformation, resistance to aging, ozone, and chemical effects, and a wide operating temperature range (-40°C to +120°C). Ethylene propylene rubber (EPDM) rubber is foamed and densely compounded. It contains unique metal clamps and tongue buckles, which is strong and durable. It plays a key role in various electrical cabinets. Silicone strip temperature resistance This technology is recognized by the world as a good process for producing extruded products. The characteristic of microwave heating is that heat is directly generated in the heated object instead of input from the outside as usual, which not only generates heat quickly, but also distributes it. Uniformity, which is beneficial to improve product quality and greatly shorten the heating time. Hot air vulcanization sealing strip: hot air sulfur has developed to strong wind type vulcanization, that is, high temperature, high speed hot air vulcanization (Tmax: 450°C and Vmax: 60m /s) The effect of flame pretreatment can also be achieved, and the safety is greatly improved. The surface of the plastic steel door and window sealing strip is smooth and clean, which not only has excellent sealing and waterproof performance, but also plays a beautiful decorative role. In terms of material selection, manufacturers with higher requirements generally choose EPDM rubber or thermoplastic EPDM rubber, according to the location And use classification (1) window glass sealing strip; (2) door sealing strip; (3) decorative strip, molding strip; (4) other sealing strips (trunk lid sealing strip, engine cover sealing strip, water tank sealing strip, Emergency door sealing strip, etc.). The skeleton sealing strip is co-extruded from dense rubber, foam rubber and steel wire/steel sheet. Also known as EPDM sealing strip (EPDM)-suitable for the special environment of -40℃ -+160℃, it has superior anti-ozone characteristics, anti-ultraviolet characteristics, resistance to chemical solvents, and various physical and chemical performance indicators far exceed Similar products. Silicone strips have high temperature resistance and high heat insulation. In the process of use, they have good heat insulation, which greatly reduces the thermal conductivity. Therefore, the heat insulation of this product is very good and can be effective To prevent the loss of temperature, three. The demand for rubber sealing strips in the automobile industry is very large. Some electronic parts and electrical assembly parts are needed, such as the sealing of windshields and automobile windows, and high-voltage cables. There are many places such as the spark plug protective cover and so on. These advantages are irreplaceable by other materials such as PVC. It can meet the needs of design and use for products with different shapes, different materials, or cold resistance, heat resistance, foaming, solid body, and special performance requirements. Automobile sealing strip production process 1. Extrusion of rubber sealing strips for automobiles is extruded by a cold feed extruder. The extrusion head has a single head, a composite (double composite and multiple composite) head and a shear head. , The screw length-to-diameter ratio of the microwave vulcanization extruder is generally 16, and the screw length-to-diameter ratio of the shear head vulcanization extruder is greater than 20. It is divided into self-adhesive type and card slot type. It is used in different doors and windows. It is more convenient and feasible in operation and installation. It does not react with any paint or cleaning agent. Customers do not need to worry about the integrity and beauty of doors and windows. Pieces: elastic pan seat and key or fixing screw 1. Use your nose to smell whether there is any peculiar smell. Normal PVC sealing strips will have a pungent smell, normal silicone rubber sealing strips will only have a little mellow smell , The smell is so small that it can hardly smell. It is widely used in the fields of box sealing and building sealing. The cold resistance, heat resistance, foaming, solid, and special properties of different application fields developed and designed by our company can meet the application needs. Installation method of inlaid wooden door sealing strip :Because the width of the saw blade or grooving knife used by each manufacturer when grooving is different, there are usually 4mm, 3mm, 2.5mm, 2.0mm, and most of them are 3mm, which is used in the purchase of seals. Be optimistic about the article. The temperature resistance of silicone strips is also called fire-resistant silicone sealing strips and fire-resistant self-extinguishing silicone sealing strips. It is known for its good flame-retardant and self-extinguishing properties. The main process is to first use high-quality silicone raw materials to form a large extruder. The silicone strip is then made by high room temperature vulcanization and drying. Compared with the general silicone strip, the high temperature resistant and flame-retardant silicone strip is different in that it needs to add flame retardant powder to the formula. The strip has super flame-retardant and fireproof performance, and it also plays a certain safety guarantee in the sealing of electronic appliances, so many people also call it a fire-proof sealing strip.
