Applications

Uses PP and HDPE as base resins with calcium carbonate and talc fillers to hit target stiffness and cost per part in housewares, crates, and caps.

PVC and HDPE dominate here, with calcium carbonate and black masterbatch controlling cost and durability in water, drainage, and cable-duct pipe.

HDPE and PP blown films rely on UV stabilizers and black masterbatch for shelf life and opacity in bags, liners, and agricultural film.

Talc-reinforced PP compounds with flame retardants and UV stabilizers meet the stiffness, heat, and safety demands of bumpers, trims, and under-hood parts.

HDPE is the workhorse resin, with UV stabilizers and masterbatch protecting containers used outdoors for chemicals, lubricants, and water storage.

PVC compounds loaded with flame retardants and calcium carbonate provide the electrical insulation, fire safety, and cost balance cable manufacturers need.

MaterialRoleEstimated Share of Batch
PP (Polypropylene)
PP (Polypropylene)
Base resin
Serves as the primary resin backbone in injection-molded housewares, crates, caps, and automotive compounds, chosen for its balance of stiffness, chemical resistance, and low cost.
40-70%
HDPE (High-Density Polyethylene)
HDPE (High-Density Polyethylene)
Base resin
Acts as the main resin in pipe extrusion, blow-molded containers, and blown film, valued for its toughness and resistance to environmental stress cracking.
40-70%
PVC (Polyvinyl Chloride)
PVC (Polyvinyl Chloride)
Base resin
Forms the base compound for rigid pipes, window profiles, and flexible cable insulation, prized for cost-efficiency and inherent flame resistance.
40-60%
Calcium Carbonate
Calcium Carbonate
Filler / extender
Reduces resin consumption and cost while increasing stiffness and opacity in pipes, crates, and PVC compounds.
10-30%
Talc
Talc
Reinforcing filler
Reinforces PP compounds with higher stiffness, heat resistance, and dimensional stability, especially critical in automotive parts.
10-20%
Black Masterbatch
Black Masterbatch
Color / UV masterbatch
Delivers uniform black coloring and UV screening in pipes, crates, and cable jacketing through a carbon-black carrier.
1-3%
Flame Retardants (Specialty Chemicals)
Flame Retardants (Specialty Chemicals)
Flame retardant additive
Slows ignition and flame spread in cable insulation, electrical enclosures, and building profiles to meet fire-safety standards.
5-15%
UV Stabilizers (Specialty Chemicals)
UV Stabilizers (Specialty Chemicals)
UV stabilizer
Protects polymer chains from UV-driven degradation, preventing embrittlement and color fade in outdoor pipes, containers, and automotive parts.
