Performance: After being stored for a period of time, it will naturally leak oil, rot, and emit a strong pungent smell.
Reason: Unqualified raw materials, incorrect raw material ratio
It is normal for TPE to leak oil, such as oil leakage after a month, but inferior TPE materials will leak oil within a very short storage time, such as within an hour, and emit a strong pungent smell, then we need to pay attention at this time! For example, after a month of storage, toys made of unqualified TPE materials will rot.
Performance: Burns at a touch and emits black smoke.
Reason: Adding toxic substances such as plasticizers
High-quality materials are not easy to burn, and there is no trace of burning on the surface after ignition.
Because the TPE material of inferior materials adds a lot of plasticizers, it is easier to ignite and emits pungent plastic black smoke. After extinguishing, the burnt area will become black and emit a pungent smell. This is a problem caused by inferior TPE materials.
This is for reference only. It does not mean that burnt products are necessarily unqualified. Many qualified products will also have this condition.
Performance: pH test paper is red
Reason: Addition of toxic plasticizers such as phthalic acid
High-quality sex toys have a pH value of 4-5 and are weakly acidic
Poor-quality toys have a pH value of strongly acidic because of the addition of phthalic acid
The inferior materials and high-quality materials are crushed and put into containers. After soaking in weakly acidic pure water for three days, the pH paper is tested and it is found that the high-quality materials are still weakly acidic. The pH test paper is yellow-green and weakly acidic, which is consistent with the pH value of the human body. However, the inferior materials add the carcinogenic additive phthalic acid. After soaking the sample materials in pure water for three days, the pH of the pure water is tested. The inferior products are red and highly acidic, which is extremely harmful to the human body.
