SYLOID® 63 FP

Features: Alta porosidad, baja higroscopicidad, adsorbe hasta 2.5 veces su peso en líquido.
Applications：Nutritional supplements (anti-caking for powdered vitamins/minerals); seasonings (moisture-proofing for salt/sugar/spices).
Compliance：满足FCC、USP/NF和日本食品添加剂标准。

SYLOID® 244 FP

Features：多功能辅料，具有防潮、抗静电和润滑特性。
Applications：Tablets/capsules (改善粉末流动，防止在制粒过程中粘连)；功能性食品（固体形式中油/液体成分的载体）

SYLOID® 72

II. TRISYL® 系列 – 食用油精炼用硅胶

FDA GRAS认证，旨在去除磷脂、金属离子和可皂化物质，以改善油的质量。

TRISYL® 150 IE

Features：高纯度合成非晶硅 (>99.9% SiO₂)。
Applications： Enzimatische Transesterifizierung (verlängert die Lebensdauer von Enzymen, produziert Öle ohne Transfette); Fischölraffination (entfernt Schwermetalle/ Gerüche).

TRISYL® 300

Features：Hochadsorptionskapazität für kolloidales Nickel und saponifizierbare Substanzen.
Applications：Post-hydrogenation treatment (removes nickel residues in vegetable oils); biodiesel pretreatment (adsorbs polar impurities).

TRISYL® 450

Features：Optimized for animal fats (e.g., beef tallow), efficiently removes collagen.
Applications:Refinación de grasas animales (mejora la claridad, reduce los olores); principalmente suministrado a los mercados de América Latina.

III. PER KASIL® 系列 – 食品级沉淀硅石

FCC认证，用于食品添加剂和补充剂中的抗结块和流动改善。

``` PER KASIL® 1450 ```

Features:Baixa densidade aparente (0,10 g/cc), alta fluidez.
Applications:

``` PER KASIL® 2000 ```

Features:高吸湿性，吸附环境湿气。
Applications:Baking premixes (maintains powder stability); pet foods (moisture-proofing for extended shelf life).

IV. 其他相关产品

SYLOBLOC® P 05:Silice amorphe synthétique pour l'anti-adhérence dans les films d'emballage alimentaire, certifié pour le contact alimentaire par la FDA (21 CFR 177.1520).
SYLODENT® 753:低硬度硅石，用于牙膏磨料，符合FCC和欧洲药典标准。

Selection Guidance

Anti-caking/Flow Improvement：优先考虑 SYLOID® 63 FP 和 PER KASIL® 1450。
Oil Refining：Use TRISYL® 150 IE or TRISYL® 300.
Liquid Adsorption：选择 SYLOID® 244 FP 或 SYLOID® 72。

All food-grade products are FDA GRAS-certified; some (e.g., TRISYL®) also meet EU EFSA and German BfR standards. Grace offers customizations for particle size, porosity, and surface treatment (e.g., SYLOID® AL-1 FP for high-humidity environments).
