Application principle and technique of foamed silica gel official:
The foamed silica gel pipe of roller shaft is foamed with closed holes, which has a separate foam hole structure. Closed hole foaming material has excellent impact resistance, anti-elasticity, softness, sound insulation, heat insulation, water resistance, steam resistance, floatability and so on, which can make the foamed silica gel of roller shaft reach a sealing resistance of water. Its main hardness at about 25 °, shaw hardness in 30 ~ 60 ° C type by customized production, raw material selection for import practice glue mixing, foaming silicone tube products inside and outside concentricity requirements have to be very high. Closed hole bubble is very uniform, roller foam silicone tube can be divided into no holes, holes, grinding. Using a unique formula can resistance to high temperature of 300 ° c, low temperature resistant to 50 °, the quality of a material is similar to the cavernous, very soft, with environmental protection, high density, grinding, ageing resistance, etc.
