Optical Brightener KCB

产品概述Overview

产品介绍Product Introduction

KCB 为萘基双苯并噁唑类荧光增白剂（C.I. 367，CAS 5089-22-5），在聚烯烃中色光表现尤为出众——强烈的蓝紫荧光赋予制品明亮高级的白，且性价比突出。批次稳定性好、加工方便，是 PP 与 PE 应用的成熟主力产品。

KCB is a naphthalene-based bis-benzoxazole optical brightener (C.I. 367, CAS 5089-22-5) prized for its outstanding color presentation in polyolefins — a strong blue-violet fluorescence that gives a bright, premium white at very attractive cost. A proven workhorse for PP and PE applications, KCB offers reliable batch-to-batch consistency and easy processing.
