01 / MgO

Magnesium Oxide

氧化镁

Active magnesium oxide is mainly used as an acid absorber in rubber and also improves the heat resistance of products. Light magnesium oxide mainly enhances heat resistance and absorbs residual catalyst acid in plastic modification. It is applied in wire and cable, halogen-containing rubber, PA nylon and other products.

• Stable performance under high friction temperature
• Helps regulate acidity in rubber and resin systems
• Improves heat resistance of composite formulations

02 / ZnO

Active Zinc Oxide

活性氧化锌

An active inorganic additive used for vulcanisation activation, opacity and UV shielding in rubber, plastic and coating formulations.

• Activates sulphur vulcanisation in rubber compounds
• Provides opacity and whiteness to plastic masterbatch
• Contributes UV absorption in coatings and films

03 / Al2Si2O5(OH)4

Kaolin

高岭土

A calcined and washed clay filler that reinforces plastics and rubber while improving surface finish and processing stability.

• Improves dimensional stability of moulded plastic parts
• Enhances surface smoothness of moulded plastic parts
• Cost-effective extender with good dispersion

04 / SiO2·nH2O

Diatomite

硅藻土

Porous siliceous material with high adsorption capacity, used as a filter aid, matting agent and functional filler. Ultrafine diatomite F-350 can absorb more oil in rubber compounds to produce ultra-low hardness products; thanks to its oil absorption, it improves wear resistance and service life in oil seals and dynamic sealing products.

• High porosity supports efficient liquid filtration
• Provides matting effect in coatings and films
• Low bulk density reduces compound weight

05 / CaSiO3

Wollastonite

硅灰石

Acicular calcium metasilicate mineral used as a reinforcing filler in friction materials, engineering plastics and coating systems. Surface-treated wollastonite delivers better mechanical strength and adhesion, and is mainly applied in fluoroelastomer and engineering plastics to improve impact resistance and strength.

• High aspect ratio reinforces plastic and friction compounds
• Supports stable friction coefficient in brake linings
• Improves stiffness and dimensional stability of moulded parts

06 / C

Natural Graphite

天然石墨

We supply natural flake graphite and cryptocrystalline graphite products for friction materials, heat conduction, thermal materials and lubrication applications. Cryptocrystalline graphite bonds well with rubber due to its crystal morphology, so ultrafine cryptocrystalline graphite is preferred for products with high strength and deformation requirements.

• Reduces wear noise in brake friction formulations
• Improves heat dissipation in thermal interface materials
• Provides dry lubrication in high-load contacts

07 / BaSO4

Precipitated Barium Sulfate

沉淀硫酸钡

A high-purity white precipitated barium sulfate powder with narrow particle size distribution, used as a functional filler in friction materials, coatings and engineering plastic compounds to improve density, chemical resistance and surface smoothness.

• High density filler that improves weight and dimensional stability of moulded parts
• Excellent chemical inertness and acid resistance in coating and compound systems
• Narrow particle size distribution supports consistent dispersion during mixing
• High whiteness maintains colour stability in light-toned formulations

08 / C8H10O4Zn

Zinc Methacrylate

甲基丙烯酸锌

A metal acrylate monomer supplied as a fine white crystalline powder, used as a crosslinking and reinforcing agent in rubber compounds to raise hardness, tear strength and dynamic modulus without excessive viscosity build-up.

• Raises hardness and modulus of rubber compounds with low viscosity increase
• Improves tear strength and dynamic fatigue resistance of moulded rubber parts
• Acts as a co-agent for peroxide curing systems
• Good dispersion in EPDM, NBR and HNBR compounds

09 / Ca(OH)2

Ultrafine Calcium Hydroxide (FKM)

超细氢氧化钙（氟橡胶吸酸剂）

An ultrafine grade calcium hydroxide developed as an acid acceptor for fluoroelastomer (FKM) compounds, neutralising hydrogen fluoride released during curing and ageing to protect moulds and maintain compound stability.

• Efficient acid acceptor for FKM and other halogen-containing elastomers
• Ultrafine particle size supports even dispersion and smooth moulded surfaces
• Reduces mould fouling and corrosion caused by acidic by-products
• Improves heat ageing resistance and compression set performance
