Straw Sports Water Bottle

 

Wrong material selection = drinking "heavy metal soup"

 

304 stainless steel: 304 is food-grade stainless steel, which is completely sufficient for daily hot water insulation.

Advantages: cheap

Disadvantages: slightly poor corrosion resistance, cannot hold acidic beverages

 

316 stainless steel: 316 is a medical-grade material, suitable for hot water, beverages and other liquids.

Advantages: antibacterial and corrosion-resistant, suitable for hot water and most beverages

Disadvantages: The price is often twice that of 304 food-grade stainless steel

 

316L stainless steel: 316L has a lower carbon content than 316, but better corrosion resistance.

Advantages: good corrosion resistance, can hold coffee or strong tea

Disadvantages: expensive, slightly lower hardness.

 

Poor quality accessories = spend money on "toxic straws"

 

Food-grade silica gel

Food-grade silica gel is an inorganic polymer colloid material formed by the condensation of silicic acid.

It is non-toxic and tasteless, with stable chemical properties.

Under normal conditions, it does not react with any acid, alkali or salt except caustic alkali and hydrofluoric acid.

 

PP plastic

PP material is polypropylene, which is a non-toxic, odorless, tasteless milky white highly crystalline polymer and one of the lightest varieties of all plastics.

It is particularly stable to water, with a water absorption rate of only 0.01% in water.

It has good formability, its melting point should be above 220 degrees, and its heat deformation temperature is around 121 degrees.

 

TRITAN material

Tritan is a copolyester with excellent performance and transparency.

It has good impact resistance, can withstand extreme temperature changes, and is not easy to break or deform.

Its excellent weather resistance and corrosion resistance can maintain the appearance transparency and physical properties for a long time.

It is widely used in food and beverage containers, baby bottles, outdoor sports equipment and other fields.
