  • How to choose safe plastic.

  • Where you can buy high quality coffee mug.


How to tell the 304 s/s & 201 s/s

1) 304 stainless steel corrosion resistance and stamping performance is far better than 201. And 304 stainless steel generally used in a complex environment, the need for strong corrosion resistance.

2) The price of 304 stainless steel is higher: in terms of price, 304 is much higher than 201. The quality of 304 is better than 201. And 304 for imported stainless steel plate, 201 for domestic stainless steel plate. So the price of 304 is naturally higher.

3) Stainless steel has better toughness: 201 stainless steel is made of relatively hard material with a bit of steel, which is easy to crack. The 304 stainless steel contains nickel, so it does not rust. 304 stainless steel is more ductile, fatigue resistance is much better than 201.

4) Stainless steel easy to rust: 201 stainless steel contains high manganese. Its surface is very bright with dark bright, high manganese rust easy. And the stainless steel coffee mug made of 304 stainless steel contains more chromium, the surface appears matte, not rust. When choosing and buying stainless steel coffee mug, put two kinds of cup together contrast distinction is very apparent.

The simplest distinction: use stainless steel identification solution, drop on stainless steel, red is 201 stainless steel, green is 304 stainless steel.

In addition, need to emphasize a point: in the judgment of stainless steel coffee mug material but also out of a mistake. That is the stainless steel thermos cup “rust”, is not absolutely not rust, but relatively under certain conditions do not rust. If consumers use it improperly (in the case of acidic substances such as tea, coffee, etc) or use it in an environment or condition that exceeds their corrosion resistance, they will naturally rust.

How to choose safe plastic

Now I’d like to introduce you to the plastic that we use on the lids of our coffee mugs. This will make you feel more comfortable about material safety.

We use food-grade PP plastic: polypropylene is non-toxic, tasteless, low density, strength, stiffness, hardness and heat resistance are better than low-pressure. You can use polyethylene at 100℃ or so. Polyethylene has good dielectric property and high frequency insulation and is not affected by humidity. Common organic solvents such as acid and alkali have little effect on it. People use it in eating utensils. And it will not dissolve harmful substances under normal and high temperature conditions.

Food-grade PP plastic can be made into any food plastic packaging, such as special food plastic bags, food plastic boxes, food straws, etc. They’re safe and non-toxic and low temperature, high temperature resistance performance. PP is the only plastic that can be put into the microwave oven for heating. And it has high strength and folding resistance performance. It will not be damaged if falling 50000 times at -20℃ from high altitude. Food grade PP sheet commonly used with frozen dumplings, microwave heating food packaging.

The material of many household items, including baby bottles, reusable water bottles and other storage containers are polycarbonate. While epoxy resin is used as a protective coating on metallic food and beverage cans, it can prevent corrosion of the metal cans and contamination of food and beverages with dissolved metals.
