Application of plastic PP in toughening and impact resistance
September 06 20:59:59, 2025
PP plastic tougheners are commonly used in general polypropylene (PP) materials, but they come with two major disadvantages:
1. **Low fracture toughness** – This means the product is prone to breaking easily when subjected to external forces. It becomes brittle and weak under stress.
2. **Poor impact resistance** – When hit by external forces—such as collisions or pressure—the material may crack, shatter, or break apart.
The price of PP raw materials and recycled PP materials varies significantly. Raw materials typically range between $10 and $12 per kg, while recycled materials fall between $7 and $10 per kg. To meet market demand, even lower prices are sometimes available. However, many of these PP materials have already been damaged during processing, which breaks down their molecular structure. To reshape them, they must go through secondary processing like granulation or pulverization. These processes often reduce the material’s toughness, impact resistance, and compatibility. As a result, there is a noticeable difference in performance based on price. The lower the cost, the lower the quality—especially in terms of toughness and impact strength.
Today’s customers have more specific requirements. Some want improved toughness, others focus on better impact resistance, and some look for enhanced cold resistance.
This makes it my job to recommend the right products for different situations—ensuring high-quality results while keeping costs as low as possible. My goal is to provide you with the satisfaction of getting exactly what you need.
To address these challenges, I recommend using **rubber-based thermoplastic elastomers**, which significantly improve toughness and impact resistance.
Our factory uses 100% raw materials and produces modified plastics that are specifically engineered by our team of professionals. Through changes in the internal molecular structure of the plastics, we enhance their toughening and impact resistance properties. We operate a full-scale production chain, from research and development to manufacturing and application.
Here’s why you should choose us:
1. We are a direct manufacturer.
2. We have a dedicated team of experienced engineers.
3. Our production team consists of skilled workers equipped with advanced machinery.
4. We offer customized solutions for plastic modification, reinforcement, toughening, and compatibilization.
5. We help reduce the number of samples and the overall cost during the functional modification process.
This is our commitment: to help you find what you need most, and to provide you with the most practical and high-quality products available.

Solar street lights have been available for quite a time now, having originally been designed for use in less developed or isolated areas, or perhaps places where the electricity supply has been disrupted by man-made or natural disasters.
The technology guiding the use of solar energy has progressed significantly to enable projects to be feasible throughout the world. The situation now is that street lights powered by solar energy can be simply and rapidly installed, giving the potential of many years of trustworthy use, with a minimum of maintenance required.
