Thermoplastic vulcanizates constitute a class of polymeric alloys that retain their ability to melt and flow,**which means they are recyclable unlike their comparable counterpart of vulcanized rubbers. These materials are**popular in automotive, consumer, construction and health-care applications, providing acoustic and mechanical**dampening as well as sealing properties. They are composed of a thermoplastic polymer matrix, like**polypropylene, and contain a dispersed dynamically vulcanized rubber phase. The degree of crosslinking**(vulcanization) must be carefully controlled and conducted at the same time as the rubber phase is being**blended into the thermoplastic matrix. Done incorrectly, the crosslinking rubber will not be blend-able or**worse, damage millions of dollars of processing equipment. Considering the complexity of the method to**prepare a thermoplastic vulcanizate, it is not surprising how infrequent new materials have evolved in this class**of polymers. BASF intends to develop a new high temperature thermoplastic vulcanizate based on a polyamide**matrix and are interested in collaborating with McMaster University in studying different aspects of preparing**this new elastomer by extrusion techniques. This new material would address heat tolerance deficiencies in the**current elastomers, used for fabricating parts needing dimensional stability at much higher operating**temperatures such as mounts in the car engine compartment, or seals for fuel cell stacks for example.**While the ultimate material includes a complex set of fillers and additives to be mixed at the same time in**order to tune properties for the customer, the immediate objective of this short evaluation project is to evaluate**the key issue of simultaneously crosslinking the rubber phase while dispersing it in chemical different**polyamide phase. A larger, more detailed study and progress along product development can not proceed till**this step is established as reasonably achievable. The proposed new thermoplastic vulcanizate will benefit**BASF as a competitor to other resins in the market. BASF has a major presence in Canada with multiple sites**in Ontario, Quebec, Alberta and Saskatchewan and its competitive strength benefits the economy of Canada.

热塑性硫化橡胶是一类保留其熔化和流动能力的聚合物合金，**这意味着它们与硫化橡胶的同类产品不同，是可回收的。这些材料**在汽车、消费品、建筑和医疗保健应用中很受欢迎，提供声学和机械**阻尼以及密封性能。它们由热塑性聚合物基体（例如聚丙烯）组成，并包含分散的动态硫化橡胶相。交联**（硫化）的程度必须小心控制，并在橡胶相**混入热塑性基质的同时进行。如果操作不当，交联橡胶将无法共混，或更糟糕的是，会损坏价值数百万美元的加工设备。考虑到制备热塑性硫化橡胶的方法的复杂性，此类聚合物中很少出现新材料也就不足为奇了。巴斯夫打算开发一种基于聚酰胺**基质的新型高温热塑性硫化橡胶，并有兴趣与麦克马斯特大学合作，研究通过挤出技术制备**这种新型弹性体的不同方面。这种新材料将解决**当前弹性体的耐热性缺陷，用于制造在更高工作**温度下需要尺寸稳定性的零件，例如汽车发动机舱中的安装件或燃料电池堆的密封件。**虽然最终材料包括一组复杂的填料和添加剂，需要同时混合以**为了为客户调整性能，但这个简短评估项目的直接目标是 评估**同时交联橡胶相同时将其分散在化学不同**聚酰胺相中的关键问题。在产品开发过程中进行更大规模、更详细的研究和进展才能进行，直到**这一步被确定为合理可实现的。拟议的新型热塑性硫化橡胶将使**巴斯夫作为市场上其他树脂的竞争对手受益。巴斯夫在加拿大拥有重要业务，在安大略省、魁北克省、阿尔伯塔省和萨斯喀彻温省设有多个生产基地**，其竞争优势有利于加拿大经济。
