PVDF J-1
—— 挤出专用PVDF树脂
1、产品简介：
PVDF J-1是一种粒状的均聚聚偏氟乙烯产品，具有较高的熔融粘度，适合于通过挤出加工工艺制备有关的PVDF制品，包括管材、片材、棒材等。
采用PVDF J-1为原料，通过适当的工艺制备而成的PVDF制品，具有良好的机械强度与韧性，在室温下不被酸、碱、强氧化剂和卤素所腐蚀，对脂肪烃、芳香烃、醇和醛等有机溶剂很稳定，在盐酸、硝酸、硫酸和稀、浓（40%）碱液中以及高达100℃温度下，其性能基本不变，并且耐γ射线、紫外线辐射，在较宽的温度范围内可以长期使用并基本保持其性能。

3、安全说明：
PVDF J-1在310℃以下热稳定性良好。在310~320℃的环境下长时间放置，会发生微量的分解，其主要分解产物为有毒的氟化氢和氟碳有机化合物。在高于370℃的环境中，产品分解速度明显加快。因此，建议在加工与使用过程中，环境温度不应超过310℃。
此外，尽管PVDF J-1具有优良的阻燃与抑烟性能，当PVDF J-1遇到火时，仍会释放出有毒的氟化氢和氟碳有机化合物。
4、包装与贮存：
包装于聚乙烯塑料袋内，再装入纸桶。每桶净重20公斤。贮存于清洁干燥的仓库内。

1、Introduction:
PVDF J-1 is a white- semitransparent pellet of polyvinylidene fluoride homopolymer with high melt viscosity, which can be well fabricated into pipe, sheet and rod by extrusion.
Made from virgin PVDF J-1, properly processed PVDF fabricated products provide good mechanical properties, toughness, and highly resistance to acid, alkali, oxidant and halogen at room temperature. The porous film is stable to aliphatic hydrocarbon, aromatic hydrocarbon, alcohol and aldehyde. At a temperature above 100℃, it shows high resistance to hydrochloric acid， sulfuric acid, nitric acid and alkaline with concentration below 40wt% in water. It is also stable to radiation and most bad environmental conditions, which lead to excellent performance for the long term.

3、Safety：
PVDF J-1 is stable at temperature up to 310℃. When it is subjected to temperature about 310~320 for extended periods of times, trace toxic hydrogen fluoride(HF) and fluorocarbon organic chemicals(FC) begin to evolve, and at temperatures above 370℃ HF and FC evolution becomes rapid. So, a temperature below 310℃ is suggested for process and use of PVDF J-1.
Furthermore, although PVDF J-1 exhibits good flame resistance, in case of fire, HF and FC can be formed, too.
4、Package and storage：
