Taking polyethylene, polypropylene, polystyrene, natural rubber, polyisoprene, SBR, ethylene propylene rubber, butyl rubber, and polybutadiene as examples, to apply this technology, it's necessary to add a considerable amount (weight ratio of 10%-50%) of microwave-heating materials, such as: (How to use PVC crosslinking agents, crosslinking agent manufacturers, which PVC crosslinking agent is better, types of PVC crosslinking agents)

① Carbon black;

② Metal powder (beware of combustion hazards);

③ Surface-treated silica;

④ Strongly magnetic and ferromagnetic powders;

⑤ Barium and lead titanates and zirconates;

⑥ Highly dipolar organic esters, phthalates, and carboxylates;

⑦ Polyoxyethylene alcohol and related ethers and esters;

⑧ Amines.

Another method involves using a small amount of catalyst (0.2 to 1%). Experts have described the use of reactive catalysts, which increase the speed of various chemical reactions, including crosslinking, by more than four times. These catalysts generate microwave-sensitive intermediate products under microwave conditions, but are inert to heat in the absence of microwaves. Application examples include curing epoxy resins via amines, anhydrides, and carboxylic acid vulcanizing agents; crosslinking silicone rubber, epoxidized rubber; sulfur vulcanization of unsaturated rubber; peroxide vulcanization; curing unsaturated polyester resins, allyl carbonate, and allyl phthalate resins, etc. (How to use PVC crosslinking agents, crosslinking agent manufacturers, which PVC crosslinking agent is better, types of PVC crosslinking agents)

In comparison, other polymers such as polyformaldehyde, plasticized polyvinyl chloride, chloroprene rubber, nitrile rubber, and acrylic rubber can be directly processed using microwaves.
