Why does silicone rubber produce bubbles after adding the curing agent?

This is a normal physical phenomenon. Liquid produces many bubbles during mixing, so vacuum exhaust bubble treatment is required.

Product Q&A

Q:What types of silicone products do you manufacture?

We produce liquid silicone, silicone rubber, and silicone oil. Our silicone varies in viscosity, hardness, and density to meet specific client requests.

Q:Do you provide free samples for testing?

Yes, we can provide free samples for client testing purposes.

Q:How is quality controlled in your factory?

We have a professional QC team that controls quality during production. All goods are 100% inspected before shipment.

Q:How can I remove bubbles during mold making?

After mixing the liquid silicone with the curing agent, place the material into a vacuum machine to remove the bubbles.

Q:How can I make my silicone mold last longer?

Choose the right liquid silicone for your product, avoid using silicone oil as it makes the mold too soft, and wait 2 hours after finishing the mold for full curing.
