一,Differences in the materials used to make imported and domestic silicone tubes
The benefits of imported silicone tubing are that it usually uses a high-purity platinum vulcanisation process, which means that the raw materials are of high purity, the tubing is more transparent (high transparency), it has little or no smell, it is more stable at high temperatures and resistant to corrosion, it is more consistent from batch to batch, and it is easier to meet strict international standards.
Some high-end domestic products have made a lot of progress, and the usage of high-quality raw materials can also meet Smooth Bore Pharma Hoses grade criteria. Domestic silicone tubing is also very cost-effective and has a short supply cycle. But some cheap products may use peroxide vulcanisation, which makes them a little less clear (semi-transparent), smells a little, and is still not as pure as imports.
When choosing, don't just look at the price. Also, check the quality of the material, the vulcanisation technique (platinum vulcanisation is best), and whether it passes food safety regulations. When there is a lot of demand, it is best to focus on products that have undergone thorough certification.
二,The test reports for imported and domestic silicone tubes are different
When evaluating imported silicone tubing, the report usually includes more information, such as foreign certifications like FDA, USP Class VI, EU EC 1935/2004, and 3-A hygiene requirements. The data from the migration test is quite reliable, and the batch traceability is very good.
High-end brands of domestic silicone tubing can give you FDA testing results, GB 4806 series domestic food contact standard reports, and ISO 9001 quality system certification. Some product certifications, on the other hand, only cover a small number of products or don't include worldwide high-end biocompatibility testing (such USP Class VI).
Overall trend: As domestic technology has improved, many high-quality domestic food silicone tubes have come close to or even surpassed the performance of imported tubes, especially when it comes to cost-effectiveness and supply chain stability.
三, Differences in Performance and Use
Pipes made in other countries usually last longer, are less likely to rip, and keep their transparency better when used at high temperatures for a long time. Pipes made in the US are better for moving food and have superior customer support after the sale. Both want flexible sanitary hoses with smooth inner walls that are easy to clean, while imported hoses are more stable in tough operating circumstances.
四, The end
The key differences between imported and domestically produced food silicone tubes are the purity of the raw ingredients, the vulcanisation process, the integrity of the certification, and the stability of the batch. High-end domestic goods have closed the gap a lot and are more cost-effective. Businesses should make well-informed decisions depending on the unique situations in which they will be used, such as transporting regular food or high-purity drugs.
Call to action: When buying something, you should ask for a full testing report and do sample testing. You can talk to expert vendors about flexible sanitary hoses or polytetrafluoroethylene pharmaceutical hoses that will work for your industrial demands.
