China Ware Materials (Royal White)
China / Porcelain – Ceramic material after heating up Kaolin (Kaolinite) Temp in a kiln range from 1200 Deg C to 1400 Deg C (2192 Deg F to 2552 Deg F).
Bone China – Ceramic material that consist of Bone Ash, Feldspathic material and Kaolin.
New Bone – Ceramic material that consist of Calcium (non-organic).
Stainless Steel Ware (Royal Steel Series)
Stainless Steel is an iron alloy containing a minimum of 11.5% chromium. In cookware and utensils, the exposure to acid (food) and alkali (detergents) is very common and thus several composition have been developed optimnally.
18-8 contains 18% Chromium and 8% Nickel.
18-10 contains 18% Chromium and 10% Nickel.
Plastic Materials (Rubbermaid)
Polyethylene (PE) – Both Low and High Density and properties include high impact resistance and long life. Used mainly on thin walled parts.
Polypropylene (PP) – Rigid plastic that is high impact resistance and long life. However, no suitable for low temperatures and is ideal for interior applications.
Polystryrene (PS) – Moderate impact strength but allows better appearance.
Polycarbonate (PC) – Aka Lexan. Transparent, brillant in colors, impact resistance and stain resistance.
Polyamide (PA) – Aka Nylon, Resistant to chemicals, high strength, very rigid and very tough, Wear resistance, high temperature usage.
Polyetherimide (PEI) – Transparent, high temperature resistance, impact resistance.
