With the promotion of environmental protection, silicone products have become increasingly common in daily life.Food-grade silicone tubing from Taihua Silicone is more eco-friendly and safer than plastic tubing.It is non-toxic, offers excellent high-temperature resistance, causes no harm to the human body in practical use, does not discolor over time, and has a long service life.Therefore, it has been widely purchased by many enterprises and merchants since its launch.
So how can we identify food-grade silicone tubing? What practical methods are available?
Tensile Test Method
There is a wide variety of food-grade silicone tubing on the market, with uneven quality among manufacturers.Consumers can use the tensile test for identification: hold both ends of the tubing and pull firmly in opposite directions.If a pungent odor is released during pulling, it means the material does not meet food-grade standards — it is ordinary silicone instead of food-grade silicone.Due to inferior material quality, the vulcanization structure is damaged when stretched, releasing an odor.Such tubing is harmful to human health and dangerous for use as drinking straws or baby products.
Smell Test Method
Genuine food-grade silicone tubing has a smooth surface, is resistant to cracking, withstands high and low temperatures, is colorless and non-toxic, does not deform when stretched, and is odorless.A supplementary method is to smell the tubing.If a pungent odor can be detected before use, it is definitely not food-grade.If it smells neutral but produces an odor when twisted or bent, the quality is also unreliable and not recommended for purchase.
