What are the expansion of the use of pu castor category?

Polyurethane caster mold or injection molding parts, within a certain range of hardness, cutting, grinding, drilling and other mechanical processing. The applicability of the process, the diversity of the polyurethane elastomer is very extensive, application domain expands unceasingly. The performance of the wide adjustable range. A number of physical and mechanical performance indexes can be adjusted through the selection of raw materials and formulations, flexible changes within a certain scope, so as to meet the unique requirements of users on the product performance. What are the expansion of the use of pu castor category? Sound-absorbing materials & ndash; — Opening of soft polyurethane foam has good sound absorption elimination function, can be used for indoor sound insulation materials, effectively reduce indoor music; Fabric composite materials & ndash; — Shoulder pads, bra sponge, cotton pad; Toys, etc. Hard hard it Rigid wheel dip refrigeration equipment & ndash; — Such as refrigerators, freezers, cold storage, cold storage house, polyurethane rigid foam is the most fantasy refrigeration equipment insulation material, use of proportion common; The main advantages: pu castor wear-resisting performance is superior. Pu castor oil resistance, ozone resistance, aging resistance, radiation resistance, good low temperature resistance, good acoustic, stick relay is strong, good biological compatibility and blood compatibility. These advantages is polyurethane elastomer in military industry, aerospace, acoustics, and biology, and other fields to achieve widespread use. Commonly known as optimal force glue, rubber spring, known as: carbamic acid polyester or polymer isocyanate resin. Wheel is a kind of between plastic and rubber elastomer, its good for the comprehensive performance of strange what is ordinary plastic and rubber does not have. What are the characteristics of the wheel? Wheel of the elastomer with good wear resistance, resistance to chemical attack, high strength, high elasticity, high low pressure, strong resistance to abrasion, shock absorption, tear resistance, radiation resistance, high load and shock absorption, etc. Good performance. Pu castor product display in the presence of water, oil and other wetting medium of working conditions, the wear resistance of polyurethane casters are often several times to dozens times of ordinary rubber materials. Metal materials such as steel, although very hard, but doesn't have to wear; Other rice huller rubber roller, such as milling, coal preparation with sieve sieve plate, stadium track the runway, forklift truck crane dynamic oil seal, elevator wheels and wheel roller skates, etc are also polyurethane elastomer. Need to mention here is that to improve the low and middle hardness, the friction coefficient of polyurethane elastomer parts, improve the bearing under the load of wear-resisting performance, can add a small amount of sulfide in this type of polyurethane elastomer aluminum and graphite or silicone oil lubricant. Processing methods diversity, wide applicability. Polyurethane elastomer can be the same as general rubber plastication, mixing and vulcanization process molding ( M) ; Also can be made into liquid rubber, mould pressing or spraying, sealing, centrifugal casting molding ( C) ; Can also be made from grain, like common plastic, use process such as injection, extrusion, calendering, blow molding, C) 。 Pu castor manufacturers & # 8203; Such as hardness, is often the user an important index of products, polyurethane elastomer can be made into Shao Er A hardness of the 20 or so soft printing rubber roller, and can be made more than 70 Shao Er D rigidity rolling roller, this is the general elastomer material is difficult to do, can suit the needs of different users. Polyurethane elastomer is composed of many flexible chain segment and rigid chain segments of the polarity of polymer materials, with the improvement of rigid chain segment ratio and the increase of density of polar group, elastomer original strength and hardness will be increased accordingly. Mold or injection molding parts, within certain hardness scale, also can be cutting, grinding, drilling and other mechanical processing. The applicability of the process, the diversity of the elastomer is widespread and has been expanding use category. Wheel material in detail using wheel material not only is an excellent polyurethane casters, the soft Flexible gasket materials & ndash; — Such as higher seat, sofa, mattress, soft polyurethane foam is a very fancy pad material information, the cushion material is one of the biggest use of soft foam dosage category, its warmth is very good. Wheel has wide scale of hardness at the same time, from shaw A10 & ndash; 100. Currently on the market has been beyond the shaw A100 or above products. In addition, the wheel has the superior performance of shock absorption, shock absorption plate, than metal spring impact resistance, it does not hurt the mold. These characteristics of wheel, very suitable for as castor material. Processing method of wheel can be the same as general rubber elastomer to plasticate, mixing, vulcanization process molding ( M) ; Wheel can also be made into liquid rubber, mould pressing or spraying, sealing, centrifugal casting molding ( C) ; Wheel can also be made from grain, like common plastic, use process such as injection, extrusion, calendering, blow molding, C) 。
