Introduction : EVERSORB 672 is used in polyurethane. Especially suitable for thermoplastic polyurethane .EVERSORB 672 prevents the processing , light and weather induced degradation of thermoplastic polyurethane . It is particularly discolor resistant for thermoplastic polyurethane. Appearance: Slightly yellowish liquidVolatility (TGA-data, heating rate 20oC/min in air) % weight loss Temperature(℃) 1 165 5 198 10 214Advantages: High heat stability. High UV light stability, does not bring smells to the polymers. Very good compatibility with polyurethane offering homogeneous distribution during processing.Application: EVERSORB 672 can be used in thermalplastic polyurethane. In general, it is recommended 0.5 to 1 wt% based on polymer weight.Discoloration Test : sample: 3mm thick injection molded thermoplastic polyurethane plaques. (clarity) Model: ASTM D1148 Test Time: 24Hrs Lamp: 300W UV light Additive: 0.6% light stabilizer Test item: Delta yellowness index (ΔYI) Toxicity & Safety : EVERSORB 672 can be safety handled without any irritation caused to the skin.Storage : EVERSORB 672 should be stored in a close system and be kept in a dry, dark place without any light exposure.----------------------------------------------------------------------------------------------------------------------------------------------------------------------他們見證永光化學(xué)紫外線吸收劑品質(zhì) ——穩(wěn)定、可靠 永光化學(xué)是知名上市化工企業(yè)集團,其紫外線吸收劑產(chǎn)業(yè)在業(yè)界具有廣泛的知名度。品質(zhì)穩(wěn)定、可靠是永光化學(xué)產(chǎn)品的重要特點。 上海蒼洪實業(yè) 20 余年專注高分子材料抗紫外線、抗黃變,為客戶提供咨詢、配方建議,彰顯專業(yè)服務(wù)。
