供应杜邦钛白粉R-103/R-104塑料级钛白粉
杜邦Ti-Pure    R-103是一种用氯化法制取的金红石型二氧化钛颜料.它的高遮盖力和非常蓝的色相使得在低用量时就能使天然色的树脂产生明亮的洁白色.R-103是专门研制以减少树脂混合料和塑料制成品在加工过程及暴露于紫外线时可能发生的色变.

R-103的特殊蓝色相在用于象ABS那样的天然有色树脂时具有特别价值.与中性色相的钛白粉相比,最多可节省30%的用量就能使最终产品达到同样要求.
R-103独特的氧化铝表处理,使之具有优秀的抗褪色性:
R-103的挥发性能适用于所有的应用所用的加工工艺,除了高温聚乙烯淋膜和聚乙烯挤出涂膜.如果有上述要求,建议使用Ti-Pure    R-101、R-104。
使用建议
Ti-Pure    R-103是一种优秀的通用型钛白粉,它适用于所有树脂体系:
表二    一性质般
遮盖力                                                                                      高
色相                                                                                            非常蓝
在下列物料中的分散性:
增塑PVC树脂                                                                              优
塑溶胶                                                                                        一般
干混合工艺                                                                                    好
熔融混合料                                                                                    优
抗絮凝作用                                                                                    非常好
抗褪色作用                                                                                    优
耐候性                                                                                            好
对于应用在那些要求高遮盖力,非常蓝的色相,优良的分散性和抗褪色性的聚烯烃或工程塑料中时,R-103是极其出色的.它的表面处理使其可用于铅盐稳定的PVC体系中,在外用场合也仅提供有限的粉化.
Ti-Pure  R-103符合NSF国际标准,适合用于塑料管材.
