Soft Mica Sheet
Model:KXT SP501
Kaxite Soft mica sheet made by mica material mixed with proper adhesive after pressed and baked. Under normal condition with a soft, heat-resistant.
Soft Mica Sheet – KXT SP501
Kaxite Sealing, a professional China mica sheet manufacturer, presents the KXT SP501 Soft Mica Sheet – a high-performance insulating material made from high-quality mica paper mixed with a non-reinforced silicone binder, then pressed and baked under controlled conditions. This flexible, heat-resistant sheet offers excellent electrical insulation and thermal stability, making it an ideal choice for heat equipment insulation, automotive gaskets, and electrical component protection.
Why KXT SP501? Soft mica sheets provide exceptional resistance to heat and even open flame up to 1000°C, combined with outstanding electrical insulation properties. They remain flexible enough to be reeled or wrapped around curved surfaces, making them suitable for applications where rigid insulation materials cannot be used. Environmentally friendly and non-toxic, these sheets are an ideal substitute for asbestos materials in automotive and industrial applications.
As a leading compression sheet supplier in China, Kaxite offers the KXT SP501 in three mica types – Muscovite, Phlogopite, and Synthetic – to suit different temperature and application requirements. Available in thicknesses from 0.1 mm to 4.0 mm and sheet sizes up to 1000×2000 mm. Request a free sample or get a wholesale quote today.

Frequently Asked Questions About Soft Mica Sheets
- Q: What is the difference between Muscovite, Phlogopite, and Synthetic mica?
- A: Muscovite offers continuous service up to 500°C (intermittent 700°C) and is the most cost-effective option. Phlogopite handles continuous 700°C (intermittent 900°C) with better high-temperature stability. Synthetic mica provides the highest heat resistance up to 900°C continuous (1000°C intermittent) and is recommended for the most demanding applications.
- Q: Is this product a safe alternative to asbestos?
- A: Yes, KXT SP501 is an asbestos-free material that provides similar or superior heat resistance and electrical insulation properties, without the health and environmental concerns associated with asbestos. It is non-toxic and safe for handling.
- Q: Can the sheet be cut or punched into custom gasket shapes?
- A: Yes, sheets with thickness below 2.0 mm can be punched into custom shapes and gaskets. Thicknesses above 2.0 mm can be machined by agreement. Contact us with your requirements for custom cutting or punching.
- Q: What certifications does the product hold?
- A: KXT SP501 is UL certified under File E248686 and conforms to IEC371-3-3 standards. Our manufacturing facility is ISO 9001:2015 certified, ensuring consistent quality and full traceability.
