As long as it is a medical product, there are many stresses on the use of raw materials, including Medical transfer pad This simple medical product is no exception. Since medical transfer pads are usually used to transfer patients, there are very strict standards for the use of raw materials. At present, the materials commonly used in the production of medical transfer pads are PVC, polyurethane PU, ordinary silica gel, etc. Let's briefly understand the characteristics of different materials.
The commonly used raw materials in the production of medical transfer pads are generally as follows:
● Silicone
Alias: silicone rubber, transparent or milky white granular solid. It has open porous structure, strong adsorption, and can adsorb a variety of substances. If water is absorbed, the moisture absorption is about 40%. If cobalt chloride is added, it will be blue when dry and red after absorbing water.
●PVC
The main ingredient is polyvinyl chloride powder, and other ingredients are added to enhance its heat resistance, toughness, ductility, etc. Alcohol and concentrated sulfuric acid are mixed 1:3 at 170 ℃ to produce ethylene chloride and ethylene, which will produce ethylene dichloride; Dichloroethylene can also be converted into chlorinated vinyl, which is the basic component of PVC. During polymerization, chlorinated vinyl molecules are linked together to form a PVC chain. The transfer pad made of this material is characterized by light weight, heat insulation, heat preservation, moisture-proof, flame retardancy, strong bending strength and impact toughness, and high elongation when broken.
●PU
Polyurethane is a common polymer material. Polyurethane is a new organic polymer material, which is widely used in many fields of national economy because of its properties. The product transfer pad made of PU material is mainly used in light industry, chemical industry, electronics, textile, medical treatment, construction, building materials, automobiles, etc. The casting polyurethane in polyurethane elastomer is used to produce anti-skid pads. The elastomer is a kind of polyurethane elastomer that is widely used and has a large output. The specific applications include printing and conveying rubber rollers; Molding cots; Oil seal, washer ball joint, bushing bearing; O-ring; Support pad; Sole, back root and toe cap; Lining; Gear, etc. The hardness range of elastomer selected is different in different application fields. The advantage of the transfer pad is its strong viscosity and adhesion.
