2、产品说明PRT＊＊＊＊电缆料系列产品是采用高分子树脂为基料，加入特殊改性剂、阻燃剂、抗氧剂、环保型防鼠添加剂和环保型防白蚁添加剂等助剂，经特殊工艺加工而制得的粒状料。产品具有优异的物理机械性能、耐候性、加工性能，同时具有优异的防鼠和防白蚁性能。

ⅱ、PRT＊＊＊＊compound series for cables and wires, based on macromolecule resin, is made into granula by special processing with adding special modifying agent, flame retardant, anti-oxygen agent, environmental friendly Rat repellent additive and environmental friendly Termite-repellent additive and etc. The products have very well physical, mechanical, weatherability and processing properties. And at the same time they have excellent Rat repellent and Termite-repellent performances.

3、产品特点 PT＊＊＊＊电缆料系列产品添加了最新型的环保型防白蚁剂，对人体皮肤无刺激性，大鼠急性口服LD50＞2000mg/kg。在大鼠体内蓄积性小，试验条件下未见致畸、致突变、致癌作用。在生产挤出过程中无污染、无刺激性气味释出、对人体无毒害作用，对设备无腐蚀作用，安全可靠。

PR＊＊＊＊电缆料系列产品添加了最新型的环保型防鼠剂，该防鼠剂不含传统的剧毒农药，采用从自然植物中提取的辛辣素类刺激性提取物，使老鼠对添加该防鼠剂的电缆料不敢咬食，从而起到驱避作用。该产品虽然在生产和敷设中对操作工人的工作环境有一点影响，（没有毒性，但有刺激性。要求操作环境通风良好，戴好手套、护目镜、口罩等，防止裸露皮肤直接接触）但其具有的无毒环保性深受用户青睐，产品已大量配套出口欧洲、美国以及应用于国内的重点工程。

ⅲ、Product characteristic

PT＊＊＊＊compound series for cables and wires is added the latest type environmental friendly Termite-repellent additives. The additives have no irritant activity to human skin. When the rat eat LD50＞2000mg/kg, The cumulation of additive in the rat body is very little. In the test condition, there is not evidence of abnormality，mutation，cancer effect. In the processing, there are no pollution, irritant odor and poison to human, and erodent to equipments.

PR＊＊＊＊compound series for cables and wires is added the latest type environmental friendly Rat repellent additives. The Rat repellent additives do not contain conventional virulent agricultural chemicals. It is the acridness extract of nature plant. The rat dare not to eat the compound when it added the additives. Although the product has a little influence of environment in producing and laying (Non toxicity, but have irritant activity. The operation environment must be ventilated conditions. And put on glove, blinkers, mask and etc. Do not let bareness skin contact the products directly). But users very favor to the environmental friendly non-toxicity of the products. The products have matched the wires and cables largely which exported to Europe and USA and used in domestic large project.

4、产品防鼠防白蚁特点 PRT＊＊＊＊电缆料系列产品添加了最新型的环保型防鼠剂，具有优异的防鼠性能。经权威机构进行防鼠食害应用对比SD大鼠试验，试验期间受试大鼠未发现任何中毒和死亡现象，活动自如、饮食正常。样品放入24小时后，对照样品塑料包层被咬开并裸露铜线；72小时后，塑料包层全部被咬掉，铜线完全裸露；连续试验14天后，加防鼠剂的塑料包层未发现任何大鼠啃咬食害的痕迹。使用于有防鼠要求的各种场合。使用于电线电缆的护套。

防白蚁性能按国标GB2951.38-86、采用击倒法。试验定时观察，90分钟后开始个别白蚁初见击倒，KT50为170分钟，240分钟100%击倒，对照组正常，24小时后测试组白蚁100%死亡，对照组全部存活。测试结束后，经介剖镜检测被测含药样品未见白蚁的咬痕。测试结果表明，被测塑料片防白蚁性能符合国标规定护层材料KT50值小于350分钟的要求。

样品按IEC502-1994及IEC840-1998中ST7热老化条件（110℃14天）进行老化后再进行防白蚁性能测试，KT50值为316分钟。测试结果表明材料在经过热氧老化后，仍具备良好的防白蚁性能，其长期时效性好。

ⅳ、PRT＊＊＊＊compound series for cables and wires is added the latest type environmental friendly Rat repellent additives.And it has very well Rat repellent performance.

After the testing of Rat repellent performance of the compound by authority organization, no mice are poisoned and dead. When putting the normal product into the test box, the plastic jacket has been bite after 24 hours, and the plastic jacket has been bite entirely after 72 hours. But the product which added the additives has not been bite after 14 days. The product is used for wires and cables as jacket where have the requirements of rat repellent.

The performance of Termite-repellent applies the knock down method and complies with GB2951.38-86 standard. Some Termites have been knocked down after 90 min, all Termite knocked down after 240 min. The result of test: The test sample team all dead after 24 hours, the contrastive team all alive. The result indicates that the Termite-repellent performance of compound is according with the GB standard (KT50 less than 350 min requirement)

When the sample after aging (according with IEC502-1994 and IEC840-1998 standard, in the thermal aging condition of 14 days/110℃), the KT50 value is 316 min. The result indicates that products still have well performance of Termite-repellent after aging. It has outstanding long-term performance.
