In the pursuit of optimizing polymer performance, chemical additives play a crucial role. Beyond their primary function, many of these additives can act as co-agents, working synergistically with primary agents to unlock enhanced properties. Bis(tert-butyldioxyisopropyl)benzene Peroxide (BIPB), known for its efficacy as a standalone crosslinking agent, also demonstrates significant potential as a co-agent in various polymer systems. NINGBO INNO PHARMCHEM CO.,LTD. is pleased to highlight the capabilities of BIPB in this advanced application, particularly for polymers like EPDM and EVA.

The Concept of Crosslinking Co-agents

Crosslinking co-agents are compounds that, when used in conjunction with primary crosslinking agents (like organic peroxides), enhance the efficiency and effectiveness of the crosslinking process. They can improve the rate of crosslinking, increase the crosslink density, modify the network structure, or improve the compatibility between the polymer and the crosslinking agent. Co-agents often lead to improved physical properties such as hardness, modulus, tensile strength, and heat resistance. The use of co-agents can also allow for reduced primary crosslinking agent dosage, potentially lowering costs and improving processing safety.

BIPB's Dual Role: Agent and Co-agent

While BIPB is a potent primary crosslinking agent, its chemical structure also allows it to participate effectively as a co-agent. When used with other peroxides or curing systems, BIPB can contribute to a more robust and efficient crosslinking network. Its ability to generate radicals and react with polymer chains helps to build a denser and more uniform three-dimensional structure. This is particularly beneficial in applications demanding high levels of mechanical strength and thermal stability.

Synergistic Benefits with EPDM and EVA

  • EPDM Rubber: In EPDM formulations, BIPB can be used alongside other peroxides or sulfur-based curing systems. As a co-agent, it can help to increase the overall crosslink density, leading to improved mechanical properties like modulus and tensile strength. It may also contribute to better heat aging resistance. Manufacturers using EPDM for demanding automotive applications can leverage BIPB as a co-agent to fine-tune their formulations for optimal performance and potentially reduce reliance on higher levels of primary agents.
  • EVA Copolymers: For EVA, especially in foaming applications, BIPB as a co-agent can enhance the efficiency of the foaming process and the resulting foam's properties. It can contribute to a more uniform cell structure and improved resilience. In applications requiring higher performance than standard EVA, using BIPB as a co-agent alongside primary agents can help achieve the desired property profile without compromising the low-odor advantage.
  • Cost-Effectiveness: The strategic use of BIPB as a co-agent can lead to cost efficiencies. By achieving a desired level of crosslinking with a lower overall dosage of primary agents, manufacturers can potentially reduce material costs.
