专业荧光增白剂出口制造商，主营 OB、OB-1、KSN、KCB——服务于 PP、PE、PVC、ABS、PS、PET 及工程塑料体系。
Professional manufacturer & exporter of optical brightening agents OB, OB-1, KSN, KCB — engineered for PP, PE, PVC, ABS, PS, PET and engineering plastics.
四款成熟产品覆盖全部聚合物体系——从通用聚烯烃到高温工程塑料。
Four proven products covering every polymer system — from general-purpose polyolefins to high-temperature engineering plastics.
OB-1 为双苯并噁唑类高性能荧光增白剂，专为高温加工体系设计。它吸收 340–380 nm 近紫外光，发射 420–450 nm 亮蓝荧光，光学上抵消基体树脂的黄相，呈现纯净高级的白。耐热约 400 °C——不分解、不升华，耐晒性优异，是 PET 与工程塑料的首选。
OB-1 is a high-performance optical brightener of the bis-benzoxazole family, specially engineered for polymer systems processed at elevated temperatures. It absorbs invisible ultraviolet light (340–380 nm) and re-emits brilliant blue fluorescence (420–450 nm), optically cancelling the yellow cast of the base resin to deliver a clean, premium white appearance.
仅 0.01%–0.05% 用量即达优异白度。
Premium whiteness at only 0.01%–0.05% dosage.
长期日晒下白度持久不泛黄。
Whites stay white under prolonged sun exposure.
稳定至约 400 °C——不分解、不升华。
Stable to ~400 °C — no decomposition, no sublimation.
PET、PC、PBT、PA——低迁移，透明件无雾度。
PET, PC, PBT, PA — low migration, no haze in clear parts.
