Some time ago, there were substances such as benzene and formaldehyde in mobile phone holsters on the Internet. Benzene and formaldehyde are carcinogens recognized by the World Health Organization and belong to volatile organic compounds. Why do some mobile phone holsters contain such substances?

The main material of the mobile phone holster is non-toxic and colorless, but why are some formaldehyde substances present? In fact, most mobile phone cases are made of plastic, silicone, and leather. Formaldehyde is usually used in the synthesis process. Residual formaldehyde will exist in the mobile phone case in a free form and will volatilize to the outside world regardless of whether it is heated or not. Many mobile phone cases with complex styles, such as flip-top holsters or various cartoon styles, require processes such as pasting, printing, and fixing. The adhesive often contains urea-formaldehyde resin, which may decompose when the temperature is too high. .

Experts say that plastic mobile phone cases are stable and non-toxic at room temperature, but as the temperature rises, the 'benzene' and 'aldehydes' in the mobile phone cases will become free. Will be released into the air and have certain toxicity.

What are the hazards of benzene and formaldehyde to the human body? ① Benzene and formaldehyde are carcinogens recognized by the World Health Organization. They are volatile organic compounds and will be released from mobile phone cases. ②Long-term, low-concentration exposure to formaldehyde can cause headache, dizziness, fatigue, reduced immunity, drowsiness, memory loss or neurasthenia, mental depression, etc. ③Long-term chronic exposure to benzene may damage the blood system and nervous system.

But the content of the mobile phone leather case is very small, with quality assurance, normal production manufacturers, after production will go through strict quality inspections, the packaging and delivery will not start until there are no problems, and once they are tested If the substances contained exceed the standard, the factory will also be strictly controlled. Therefore, when choosing a mobile phone case wholesale, you need to find a reliable manufacturer
