Why does silicone rubber produce bubbles after adding curing agent?

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

Product Q&A

Q:What silicone products do you make?

We produce liquid silicone, silicone rubber, and silicone oil. Different molds result in varying viscosity, hardness, and density to meet client requests.

Q:Do you offer free samples?

Yes, we can provide samples for testing.

Q:How do you control quality in your factory?

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

Q:How to remove bubbles during mould making?

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

Q:How to get a good silicone mould for longer use?

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