Injection Molding Resin: PP, HDPE and Impact Copolymer
PP, HDPE and impact copolymer grades for caps, crates, containers and appliance parts.
Molders run on cycle time, scrap and cost per part. BASTONE supplies injection and blow-molding resin from PetroChina, and PP additive masterbatch to adjust clarity, stiffness and colour.
Common Problems in Injection Molding & Household
What buyers ask us about, and the grades that solve it.
Thin walls that do not fill
Thin-wall parts need high melt flow. H9018 runs at 55 g/10 min for thin-walled injection molding.
Recommended grades
Brittle parts in cold storage
Impact copolymers keep toughness at low temperature. K8003 and K9928H cover containers, battery shells, drums and appliance housings.
Recommended grades
Slow cycles and heavy parts
Nucleating and stiffening masterbatch speed PP crystallization, so parts cool faster and walls can go thinner.
Recommended grades
Hazy PP that looks cheap
Clarifying masterbatch cuts haze and raises gloss in PP cups and containers.
Recommended grades

CAM-3010 Clarifying Masterbatch
Clarifying masterbatch at 1 to 3 percent for PP injection molding, sheet and thermoforming, with FDA and GB compliance for medical, laboratory and household plastics.
View grade →CA-61S Clarifying Agent
Organic clarifier and nucleator dosed at 0.15 to 0.25 percent that shrinks spherulite size to cut haze and raise gloss, stiffness and heat deflection temperature in PP.
View grade →CAM-3080 Stiffening Masterbatch
Stiffening masterbatch that raises rigidity by roughly 30 percent and heat deflection temperature by close to 20 °C, so parts can be downgauged and cycle times shortened.
View grade →NA-4A Polypropylene Nucleating Agent
Alpha nucleator dosed at 0.04 to 0.3 percent that raises crystallization temperature and shortens injection molding cycle times.
View grade →Injection Molding & Household FAQ
What kind of resin is used for injection molding?
Common choices are PP, HDPE, polystyrene and ABS. BASTONE lists HDPE for caps and crates, PP homopolymer for thin walls, and impact copolymer PP for tough parts such as battery shells and appliance housings.
How do I choose between PP homopolymer and impact copolymer?
Homopolymer gives stiffness and high flow, as with H9018. Impact copolymer adds toughness at low temperature, as with K8003 and K9928H. Choose by the impact and temperature requirement of the part.
Can additives make PP clear?
Clarifying and transparency masterbatch raise clarity and gloss in PP. The masterbatch grades recommended on this page, such as CAM-3010 and CA-61S, list their dosage on the product page.
