custom machining 99% Al2O3 Alumina Ceramic gas distributer
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
The outstanding characteristics of 99 alumina impact polystyrene are easy processing, excellent dimensional stability, high impact strength and high rigidity. For HIPS only heat resistance. There are certain limits in oxygen permeability, ultraviolet light stability and oil resistance. Chemical and performance Impact polystyrene is prepared by dissolving polydiene rubber in styrene monomer before polymerization. Although the suspension polymerization method can be used to prepare HIPS, the bulk polymerization method is currently used in the industrial production of HIPS. In the bulk polymerization process, the mixture of styrene monomer/rubber/additive passes through a series of reactors with a conversion rate of 70-90%. In the polymerization reaction, heating or adding initiator is required to complete the reaction, and then heating in a vacuum to remove volatile residual monomers from the resin, and then pelletizing and selling.
The impact polystyrene performance test is divided into several levels according to its relative impact strength:
The impact strength of notched cantilever beams of medium impact resistance grade is generally 0.6-1./i;
The impact resistance of the high impact resistance grade is 1.5-2.5ftlb/in;
The impact strength of the extremely high impact resistance is >2ftlb/in.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
