A practical evidence checklist for RFQ preparation and supplier evaluation.
Compare the published product scope and source details, then include your specifications and quantity in an enquiry.
2 companies list this product among what they make. Company figures are quoted from each company's own website; every card states where the relationship came from.
The official RH-SP-5 product page lists polymethylsilsesquioxane silicone resin powder with 5 μm average particle size, refractive index 1.42, oil absorption 55–65 g/100g, 20 kg drums, for cosmetic formulations, and the FAQ states it is a manufacturer with its own factory; the About page on the same domain states it was founded in 2004 and develops and produces silicone materials in 8 series and over 100 grades with annual output of 30,000 tonnes. Coating or adhesive uses and compliance certificates must be verified per order.
Explore company information and manufacturing capabilities, then discuss the scope of your project with a relevant supplier.
Ask for use case, specification boundaries, supplier type, and RFQ preparation information for this product.
The median particle diameter (D50) is typically in the range of 15–60 µm. This parameter affects application uniformity and film thickness. Confirm the exact value for the specific grade with the supplier.
The recommended cure temperature range is 150–250°C. The powder melts at 120–180°C, and cross-linking occurs within this range. Actual curing conditions depend on the formulation and application method.
It offers thermal stability up to 250–350°C continuous service, dielectric strength of 20–40 kV/mm, and water absorption ≤0.1%. These values are typical and should be verified for the specific product.
Store in a sealed container below 25°C. Under these conditions, shelf life is typically 12–24 months. Keep away from moisture and contaminants to maintain performance.
