In the silicone foaming industry, "platinum foaming" refers to an advanced process that uses platinum catalysts (platinum complexes) to catalyze the cross-linking foaming reaction of silicone.
2. What does "platinum foaming" mean in the industry?
For producers and end users, "platinum foaming" represents the following key points:
1. Outstanding environmental protection and safety performance, odorless and non-toxic: This is its most core advantage. Because no volatile by-products are produced, the products made (such as kitchenware, baby products, underwear pads, medical gaskets) have no unpleasant smell and are safer for the human body. Biocompatibility: This feature enables it to pass strict medical and food contact certifications (such as FDA, LFGB), making it the preferred choice for high-end application fields.
2. Top-notch product quality anti-yellowing: The platinum catalytic system does not produce by-products that cause the material to turn yellow, so the products can remain as white as new even after long-term use or exposure to ultraviolet rays, with a better appearance. High purity: The foam cells are purer and the physical properties are more stable.
3. Higher production process requirements and strict raw material control: As platinum catalysts are highly prone to "poisoning" and deactivation, all raw materials (raw rubber, fillers, color pastes, etc.) during the production process must be ensured to be "platinum-specific", and substances containing nitrogen, phosphorus, sulfur, tin and other elements must not be mixed in. Clean production environment: Extremely high cleanliness requirements are imposed on production equipment to prevent cross-contamination. High technical threshold: More precise process control and more professional production knowledge are required.
4. Higher cost: Platinum is a precious metal, and the cost of its catalyst is much higher than that of peroxides. This means that silicone products foamed with platinum are usually more expensive.
