Do You Know What the Use of Glass Wool Insulation Material Is?

From the present day, we can see that Glass Wool insulation material is used in many aspects of daily life. Its thermal insulation properties make it widely used in daily life or work. The most common is that in colder winters, people can use this product to wrap their own water pipes. This can ensure that their water pipes are not frozen, and then the water between them can be kept flowing for as long as possible. Glass Wool Because of its shearability, glass wool insulation materials can be trimmed according to their own needs, and products of different sizes can be cut and used in different places. For example, in this relatively cold place in the Northeast, people can wrap this product on their own roofs, make their houses adhere to a certain temperature, and fully play the role of heat insulation of this product, bringing comfort and comfort to their lives. convenient. In addition, glass wool insulation materials are also used more locally. With the extensive use of this in

Neoprene vs EPDM: What's the Difference?

Both neoprene and EPDM are materials used in the manufacture of conveyor belt systems. While neoprene is most commonly used in the industry, many companies are turning to EPDM because using it overcomes many of the challenges associated with using neoprene. What is neoprene? Neoprene is made through the polymerization of chlorine. Characterised by its chemical stability, flexibility over a wide range of temperatures and resistance to degradation, the material was originally intended as a petroleum-based alternative to natural rubber. Its durability and flexibility make neoprene suitable for a wide range of everyday products - such as sports and medical equipment, technical coverings and sleeves, diving suits and safety gloves - as well as for a variety of outdoor applications - including as hoses, gaskets, seals, and gaskets. -including as hoses, gaskets, seals, coatings and linings. Huamei EPDM rubber foams include semi-closed cell supersoft and supersoft foams; closed c

What Is the Difference Between Extruded Board and Foam Board?

Extruded plate (XPS), based on polystyrene resin as raw material, through a special process of continuous extrusion foaming molding hardboard, its internal structure for independent closed bubbles, is one kind has high pressure, water absorption, moisture, breathable, lightweight, corrosion resistance, long service life, low coefficient of thermal conductivity, excellent environmental protection heat preservation material performance. Extruded polystyrene (XPS) insulation board is widely used in wall insulation, flat concrete roof, and steel structure roof insulation, low-temperature storage ground, parking platform, airport runway, highway and other fields of moisture-proof insulation, and control ground frost heave. 1. Excellent and long-lasting thermal insulation The extruded board has a thermal conductivity of 0.028w/MK, which has the characteristics of high thermal resistance and low linear expansion rate. Its thermal conductivity is far lower than other insulation materials su
