1. How much is a kilogram of toughening agent?
If the toughness of the plastic is not enough, toughening agents can be added for modification, which is used in the production of many plastic products. Toughening agent, so how much does it cost per kilogram?
There are many types of toughening agents on the market. Different types of toughening agents will be different in terms of ingredients, functions, addition ratios, etc., and the prices will also be different. In addition, the properties of toughening agents Factors such as manufacturer, purchase quantity, location, etc. will also affect the price of tougheners.
The price of tougheners generally ranges from five or six yuan per kilogram to more than ten or twenty yuan per kilogram. The more expensive ones are thirty or forty yuan per kilogram. If you purchase in bulk, you can contact the manufacturer to negotiate the price.
2. What factors should be considered when purchasing plastic tougheners
There are many plastic toughening agent products and there are many manufacturers. When choosing, you can mainly consider the following aspects:
1. Toughening effect
This is the core requirement for the selection of tougheners. After adding tougheners, how much the impact strength can be improved, whether it meets the product usage standards, whether it can reduce the low-temperature brittleness of plastics, etc., and whether the tougheners can solve the problem. These pain points are the factors most worth considering.
2. Compatibility with plastics
If the compatibility of the mixture of plastics and tougheners is too high, the two will be completely at the molecular level. When mixed, the toughener becomes a plasticizer and cannot form two phases, so the impact strength cannot be improved. On the contrary, if the compatibility between the two is too small and uniform dispersion cannot be achieved, the toughener will lose its effect on the plastic. The adhesion force cannot absorb impact energy, and the impact strength cannot be improved, so the toughening agent needs to have a certain compatibility with the plastic.
3. Additive dosage
On the basis of ensuring that the performance meets the requirements, the less the toughening agent is added, the more materials can be saved. Cost will bring more economic benefits to the enterprise.
4. Are there any side effects?
Does the toughening agent affect the physical, mechanical and other properties of plastics?
5. Other properties
Such as the oxidation resistance, weather resistance, and temperature resistance of the toughening agentand processing stability, which can help extend the service life of the product.
6. Price
Of course, the product price also needs to be considered in terms of raw material costs.
