Why does the mold silicone have poor tension?

Poor tension results from adding too much silicone oil to reduce viscosity, making the rubber too soft. This reduces tear strength and durability. Avoid excessive oil addition.

Why does the mold surface have traces or unevenness?

Surface issues usually arise from an unpolished original model or uneven application of release agent. Ensure the model is smooth and the release agent is brushed evenly.

What are the main applications of this mold silicone?

It is widely used in toy, gift, furniture decoration, character reproduction, resin handicrafts, candle making, glass products, and sculpture industries for mold making and replication.

AI-Powered supplier vetting

SummaryDongguan Gangtian Polymer Materials Co., Ltd. is identified as a China-based manufacturer of silicone and polymer materials, established in 2011, with 59 employees and a 6,000 m² manufacturing plant. Its product portfolio includes RTV 2 silicone rubber, LSR, silicone oil, silicone ink, pigments, and electronic potting compounds. The supplier reports more than 10 production lines and annual capacities totaling 6,900 tons across listed products, as well as exports since 2016 with 21%–30% of sales from exports. It holds an ISO 9001:2015 certificate and reports six R&D engineers and six to ten quality-control staff. The information supports strengths in certification, product breadth, production scale, and international market experience. However, the provided evidence does not sufficiently establish financial credibility, customization capability, or specific customer cases. After-sales capability is indicated by a stated focus on after-service but is not documented in operational detail.

Supplier typeThe supplier is explicitly identified as a manufacturer and as a professional manufacturer of RTV 2 liquid silicone rubbers. Its company type is also described as a limited company, with operations in Dongguan, Guangdong, China.

CertificationsThe supplier holds an ISO 9001:2015 certificate for supplier management systems. This is explicit evidence of a formal quality-management certification.

R&D capabilityThe supplier describes an R&D focus on innovation, reports six R&D engineers, and states that it has developed performance-enhancing silicone solutions. These statements support an established R&D function, although no patents, laboratories, or quantified R&D results are provided.

Production capacityThe supplier reports more than 10 production lines, a 6,000 m² manufacturing plant, and product capacities of 2,500 tons each for tin and platinum silicone rubber, 1,000 tons for silicone oil, 800 tons for electronic potting compound, and 100 tons for pigment. It also states production capacity above 500 tons per month, indicating substantial manufacturing capability.

Product Q&A

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

Weak tear strength is often caused by adding too much silicone oil or catalyst. We recommend adding no more than 5% catalyst (2% is ideal) and avoiding excessive silicone oil to maintain tension and tear strength.

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

This condensation silicone rubber solidifies by absorbing moisture from the air. To fix this, add 0.05% water to the silicone rubber and stir briefly at low speed before use.

Q:Why does the silicone mold get burnt out?

Burnt molds occur when using unsaturated resin, which generates heat. You must demold the product within 3 minutes. Our silicone rubber includes special materials to resist high temperatures.

Q:Why does the mold appear oily?

The silicone itself does not emit oil. Oiliness is caused by adding composite silicone oil (silicone oil mixed with white mineral oil) during operation, as white mineral oil is a petrochemical product.

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

Reusability issues often stem from adding too much silicone oil or catalyst, or using high-hardness rubber for small, intricate designs. Proper mixing ratios and hardness selection are crucial.
