GM5049B是一种黑色高分子量高密度聚乙烯。它是一种高性能树脂,用于要求使用寿命达50年的压力管道中。GM5049B具有优异的加工性能,同时具有优异的韧性、耐化学腐蚀性和耐环境应力开裂性。GM5049B还将在户外应用中提供优异的抗紫外线照射效果。GM5049B设计用于挤压成各种管道和配件尺寸,需要高密度聚乙烯100型树脂。GM5049B适用于工业、农村和采矿应用,包括饮用水的各种流体输送。应通过适当的性能测试来确定在任何应用中的适用性。GM5049B的设计符合PE 100型化合物的要求,并已被澳大拉西亚聚烯烃管道系统公司接受为符合AS/NZS 4131:1997的要求,拟用于符合AS/NZS 4130的管道。材料不符合第8条。在AS/NZS 4131:1997中,50°C下的长期静水强度尚未确定。它完全符合标准草案AS/NZS4131(1999年草案)。GM5049B适用于食品接触应用,符合AS2070的要求。 GM5049B is a black high molecular weight High Density Polyethylene. It is a high performance resin for use in pressure pipes where service life to 50 years is required. GM5049B offers a balance of excellent processing characteristics along with outstanding toughness, chemical resistance and environment stress crack resistance. GM5049B will also provide excellent resistance to the effects of Ultra-Violet light exposure in outdoor applications. GM5049B has been designed for extrusion into a full range of pipe and fitting sizes, where High Density, PE 100 Type resins are required. GM5049B is suitable for use in the transport of a wide range of fluids for industrial, rural and mining applications, including potable water. Suitability for use in any application should be determined by appropriate performance testing. GM5049B has been designed to meet the requirements for PE 100 Type compounds and has been accepted by Australasian Polyolefine Pipeline Systems Inc. as meeting AS/NZS 4131:1997 and is intended to be used in pipes conforming to AS/NZS 4130. The material does not comply with clause 8. of AS/NZS 4131:1997 in that the long-term hydrostatic strength at 50°C has not been determined. It does comply in full with draft standard AS/NZS4131 (draft 1999). GM5049B is suitable for food contact applications and conforms to the requirements of AS2070. |

JBS USA公司呈现食品塑料净化风险
2018-05-07 据外媒报道,美国农业部(USDA)近日表示,如果光是召回2亿个鸡蛋和大量切碎的生菜还远远不够,3.5万磅绞碎的生牛肉也应该被召回。获悉,这一召回最先由JBS USA公司的食品塑料污染风险引起。那些可能遭到塑料污染的牛肉在各种不同的包装下对外出售,大部分贴的则都是Kroger食品商店的商标。 召回由USDA食品安全与检查服务部门(FSIS)宣布,受影响的产品都是在2018年3月22日生产的。此次召回的产品只涵盖生牛肉,所以先前已经煮过的冷冻牛肉是安全的。 US |
