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 viscosity, hardness, and density vary based on the mold requirements to meet client needs.

Q:Do you offer free samples to clients?

Yes, we can provide free samples for testing purposes.

Q:How do you ensure quality control 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 get a silicone mold that lasts longer?

Choose the right liquid silicone for your product, do not use silicone oil as it makes the mold too soft, and wait 2 hours after finishing the mold for full curing.
