Applications
Outdoor product processing is the target application across the ABS, HIPS, PP, and PE families. Practically, that covers garden and patio furniture, outdoor storage boxes and bins, agricultural films and irrigation components, playground equipment, exterior automotive trim, construction site barriers and traffic furniture, and molded housings for outdoor electrical enclosures.
Injection-molded outdoor furniture in PP and ABS drives most demand. Parts sit in direct sun for years and carry structural load — a chair frame or a table leg fails dangerously when the polymer embrittles. The 3500–5000 hour aging window with over 90% mechanical retention gives molders a defensible service-life argument, and the 220–280 °C temperature resistance means the stabilizer package survives typical ABS melt temperatures without degrading during residence time in the barrel.
Extruded PE and PP profiles for construction and agriculture face a different stress: long UV exposure combined with mechanical flexing. Sun resistance at 7–8 addresses color hold across those long exposure cycles, which matters for products where fading signals age to the end customer even when the part remains structurally sound.
For processors running dark or saturated colors, the 1:20 or 1:25 addition ratio keeps the stabilizer contribution proportional to pigment loading. Higher pigment loading means higher masterbatch loading, so the additive package scales with the color depth rather than requiring a separate stabilizer letdown.
Why Choose BASTONE
BASTONE manufactures the masterbatch at its own Hangzhou production facility rather than sourcing it from a third-party compounder. Pigment selection, additive dosing, twin-screw compounding, and pelletizing all happen under one quality system, so batch-to-batch color and additive consistency traces back to a single production record. Buyers who have dealt with trading houses reselling unnamed compounders know the difference — when a shade drifts or aging results slip, there is a specific line and a specific technician to call.
The R&D center behind the product handles formulation work that pure distributors cannot. Custom shade matching, adjusted stabilizer loadings for tropical versus temperate service, and alternate carrier resins for specific processing equipment all run as development projects rather than special requests passed up a supply chain. BASTONE's group structure spans organic chemicals, polymers, and specialty additives, which means the stabilizer and antioxidant inputs come from a team that understands them chemically, not just commercially.
Pricing reflects direct manufacturer supply. No intermediary margin sits between the production line and the export invoice. Zhejiang Bastone Technology Co., Ltd handles the export side directly, with over ten years of documentation and logistics experience covering flexible trade terms, container consolidation, and the certificate packages that customs clearance requires in most destination markets.

Values shown reflect typical production data for the standard grade. Ratings, aging results, and processing windows vary with pigment system, base resin, and climatic exposure conditions — processing trials on the intended resin and equipment are recommended before series production.
