What aspects should be paid attention to in summer and winter for the same Automotive Wiring Harness Protection Sleeve formula

The formula of the same Cable Sleeve is generally inconsistent in summer and winter due to the seasonal ambient temperature. To distinguish between the two, I usually adjust the amount of accelerator and vulcanizer, and the amount in summer is less than that in winter. I don`t know how you do it, because we encountered a similar situation when refining Automotive Wiring Harness Protection Sleeve: the formula with good performance in winter, the scorch time shortens in summer, and the extruded products have cooked rubber particles or different sizes. tumors, which affect the surface quality of the product and the comprehensive quality problem that can only be discovered after a delay. Therefore, measures have been taken to reduce the amount of accelerators and Automotive Wiring Harness Protection Sleeve to prolong the scorch time and ensure correctness. The vulcanization time does not change too much to ensure the stability and production efficiency of the extrusion process. Practice has proved that the effect is still good.

The main consideration in summer is scorch, and the scorch time in summer should be longer to prevent vulcanization during rubber mixing or storage. If the formula is properly matched, there is generally no problem. Our formula is not divided. We have encountered this situation now. The performance of the formula is very good in winter. In the past few days, the scorch time is short, and there is cooked glue when extruded, which is a headache to handle. If the formula is designed properly, it can be used regardless of season. If the formula blindly pursues rapid vulcanization to reduce costs, it will be easier for the above-mentioned problems to occur.
In short, due to limited conditions, we do not have a large enough air-conditioned room. When the order is large and the delivery time is short, the rubber to be mixed is relatively large, and it is generally stored directly in a workshop without cooling measures, so it is easy to cause scorching of the rubber. Shortening of time. If there is no effective temperature-controlled storage warehouse, the formula must be adjusted in summer and winter. Otherwise, it goes without saying that the weather is scorching. I have added 0.5 parts of anti-scorch agent CTP, and the effect is not bad, but it is better to adjust the vulcanization system formula. Reducing the amount of accelerator and automotive wire harness protective cover to prolong the scorch time will definitely affect the physical properties of the formulation, the degree of cross-linking will be reduced, the TB will definitely be reduced, and the T90 will be extended and so on.
Any adjustment will affect some physical properties more or less, as long as these effects are still within the scope of customer requirements. In addition to the editor's adjustment method, it is also possible to add some anti-scorch agents or use slower accelerators. No matter what adjustment method is adopted, it is still the same sentence: as long as the process purpose can be achieved and the physical properties are still within the scope of customer requirements, it is a feasible method.
