Why does the mold appear oily?

The silicone itself does not emit oil. The oil is caused by adding composite silicone oil (mixed with white mineral oil) during operation.

Why does the silicone mold have traces, streaks, and unevenness?

This happens if the original model is not smooth or polished, or if the release agent is not applied evenly.

What are the wonderful usages of mold silicone?

It is widely used in toy, gift, furniture, character reproduction, building decoration, resin crafts, candle making, plastic toys, gypsum crafts, glass products, and sculpture industries.

Product Q&A

Q:Why can the silicone mold be reused only for a few times?

Common reasons include adding too much silicone oil which destroys molecular weight, adding too much catalyst (more than 2% for tin cure) which speeds up operation and reduces strength, or using the wrong hardness for the product design.

Q:Why does the silicone mold get burnt out?

This occurs when using unsaturated resin without demolding within 3 minutes, as the resin generates great heat during curing. Our silicone rubber contains special materials to resist high temperatures.

Q:Why does the silicone mold appear dry outside but wet inside?

This is typical for condensation silicone rubber which solidifies by absorbing moisture. To fix this, add 0.05% water and stir briefly at low speed before use.

Q:Why is the tear strength of silicone molds weak?

Weakness is caused by adding too much silicone oil, adding excessive catalyst (recommended max 5%, ideally 2%), or using the mold prematurely before the recommended 24-hour curing period.

Q:Why does the mold silicone have poor tension?

Poor tension results from adding large amounts of silicone oil to reduce viscosity, making the rubber too soft and reducing its durability and service life.
