        basic introduction

        Chemical additives, especially chemical additives required by a certain industry, which are not limited to metal processing additives, plastic additives, papermaking additives, construction additives, water treatment additives, coating additives, leather additives Agent, textile printing and dyeing auxiliary, etc.

        Testing products

        Rubber additives:

        Various inorganic fillers, vulcanization aids (vulcanizing agents, crosslinking agents, accelerators, activators and anti-scorching agents), protective aids (antioxidants, anti-ozonants, anti-flex cracking agents, light stabilizers, UV Light absorbers, harmful metal inhibitors, physical antioxidants, termite inhibitors, mildew inhibitors) reinforcement aids (carbon black, white carbon black, metal oxides, inorganic salts, resins) process operation aids (plasticizers) , Solubilizers, plasticizers, softeners, leveling agents, lubricants, dispersants, tackifiers, release agents, release agents) special additives (colorants, foaming agents, defoamers, thickeners, Ointment, wetting agent, emulsifier, stabilizer, coagulant, heat sensitive agent, anti-webbed agent, preservative, preservative, flame retardant, antistatic agent, fragrance, etc.).

        Plastic additives:

        Plasticizers (orthophthalic plasticizers, etc.), heat stabilizers, antioxidants (158, 1010, etc.), light stabilizers, flame retardants, foaming agents, antistatic agents, mildew inhibitors, colorants, Brightener, filler, coupling agent, lubricant, mold release agent

        Paint and pigment additives:
