abrasion resistant aluminum oxide ceramic block brick
Reputation depends on quality, quality comes from Hard!
Alumina Ceramics:
Some HIPS grades of alumina ceramics have an impact strength value of up to 6ftlb/in, but this resin is usually used in blended resins to improve the impact strength of low-strength grade resins.
Other important performance testing matters of standard HIPS are as follows: bending strength 13.8-55.1MPa; tensile strength 13.8-41.4MPa; elongation at break 15-75%; density 1.035-1.04 g/mL; Vicat softening point 185— 220°F. [2]
The only industrially mixed HIPS alloy is its blend with polyphenylene ether. The heat resistance and toughness of this blend are outstanding, but the product price is much higher than that of HIPS alone.
The continuous development of polystyrene technology enables the production plant to produce grades with more outstanding performance than standard PS. Many properties of polystyrene cannot be achieved at the same time. If you want to improve the impact strength, you have to sacrifice gloss. Some new resins appearing at present have the glossiness of ABS and high toughness. Some grades, such as those that can withstand various oils and fats when packaging food, and chlorofluorocarbon (CFC) foaming agents when used in refrigerators, have also been developed. Flame-retardant (UL V-0 and UL 5-V), impact-resistant polystyrene has been produced and widely used in TV housings, business machines and electrical products. The processing operation of these resins is easier than many flame retardant engineering resins, and the price is lower.
properties: High hardness, high strength, wear resistance, corrosion resistance, high temperacture (1600°), good thermal diffusivity, good insulativity, low cost etc.
