About this product

Product information from the supplier.

Premium 325 Mesh Sericite Mica is a high-purity, fine-grained mineral engineered specifically for high-end plastic and cosmetic applications. Characterized by its unique layered structure and exceptional reflective properties, this professional-grade mica powder provides a silky-smooth texture and a radiant, light-diffusing finish, making it an indispensable ingredient for modern beauty formulations and advanced polymer engineering.

Beyond its aesthetic appeal, our Sericite Mica serves as a functional additive that enhances the physical properties of materials. In plastics, it improves tensile strength, heat stability, and dimensional stability, while in cosmetics, it offers a non-irritating, lightweight alternative to synthetic fillers. With ISO-certified production and patented technology, we ensure a consistent particle distribution that meets the strictest industrial standards for purity and performance.

Frequently Asked Questions

Q: What makes Sericite Mica suitable for cosmetics?

Sericite is valued for its soft, flaky nature and reflective properties, which provide a silky texture and a radiant, dewy finish to makeup products without irritating the skin.

Q: How does 325 mesh sericite improve plastic performance?

It enhances tensile strength and bending modulus while improving size stability, which significantly reduces shrinkage, warpage, and tortuosity in polymers like PP, ABS, and PVC.

Q: What is the difference between dry ground and wet ground mica?

Dry ground mica maintains natural properties through physical grinding. Wet ground mica undergoes washing and purification, resulting in higher purity, whiteness, and glossiness.

Q: Can Sericite Mica be used in functional masterbatches?

Yes, it is highly suitable for functional masterbatches and plastic engineering to improve insulativity, fire resistance, and overall optical performance.

Q: Is this product safe for sensitive skin applications?

Absolutely. Sericite is non-irritating and is frequently used as a natural, skin-friendly alternative to synthetic binders in clean beauty products.

Q: What packaging options are available for bulk orders?

We offer standard 25kg PP or paper bags, as well as 500kg to 1000kg jumbo bags. Customized packaging is also available upon request.
