This is an interview of uncle ma, who is the storage manager in Coace.
Do Compatibilizers/Tougheners meet FDA testing?
Theoretically speaking, most of our compatibilizers, toughening agents and so on. By adding in some specific materials, a raw material added in compliance basically can meet the requirements of the FDA. But there are several cases to be divided here. POE grafting maleic anhydride itself is hard to go with FDA. The difficulty in passing is not caused by grafting, but rather by the solubility of cyclohexanone in one of the tests. So it depends on how you choose.
Cómo controlar la temperatura de extrusión del compuesto de nailon doble 6 simple 6 más fibra
The extrusion temperature is according to a processing of nylon double 6, as close to double 6 as possible, but can be slightly lower than double 6. One principle is to check the melting state before adding glass fiber.
¿Cuáles son los indicadores de dureza plástica?
You just have to focus on the notched impact and the fracture growth rate If these two indicators are high then the material has a good toughness If the material is not tough enough you need to add a toughening agent Our W1A toughening agent.
How should you choose this alloy compatibilizer for PP and PA？
This issue gives you two options.
Firstly, if your base material is copolymer Pp，
then I would recommend you to try our
Pp graft maleic anhydride compatibiliser
because it is compatible with the material.
The toughness of the material itself is guaranteed.
So we mainly consider its compatibility.
Secondly, if your base material is homopolymer PP.
then I would recommend you to try
This POE intermixing PP toughener.
Because the impact strength of the material is not guaranteed.
