Materials
We offer a variety of material options for our insulated bottles. Our stainless steel options include 201, 304, and 316, while our plastic parts include Tritan, PP, AS, and TPU. Each material offers different prices, levels of quality, and durability, ensuring that our customers can find a product that meets their needs and fits within their budget.
SUS 201
A type of austenitic stainless steel comprising 16% chromium, 3-5% nickel, and 1-2% manganese. It has more hardness, more susceptible to corrosion than the stainless steel in grade 304, and The surface is not as shiny as the stainless in grade 304. The durability of the stainless steel in grade 201 is relatively high.
SUS 304 (SUS 18/8)
SUS 304 material is the most commonly used stainless steel, containing 18% chromium and 8% nickel. It is food-grade stainless steel. It can maintain good strength and heat resistance in high-temperature and low-temperature environments and has good corrosion resistance, weldability, cold workability, and mechanical properties in a calm atmosphere.
SUS 18/10
SUS 18/10 is a type of austenitic stainless steel comprising 18% chromium and 10% nickel. It offers excellent corrosion resistance and is also suitable for food-related applications.
SUS 316
SUS 316 Stainless Steel contains 16% chromium, 10% nickel, and 2% molybdenum. It is surgical-grade stainless steel. Compared to SUS 10/18, it has better resistance to common acids and offers more flexibility for applications with different shapes. It is also more costly compared to the other materials.
Tritan
Tritan is a lightweight, durable, and recyclable plastic type.
PP
PP (Polypropylene) is a type of plastic resin that is lightweight and corrosion-resistant.
AS
AS (Acrylonitrile Styrene) is a thermoplastic polymer used in various applications due to its strength and flexibility.
TPU
TPU (Thermoplastic Polyurethane) is a strong and flexible plastic with excellent resistance to oil and chemicals.
