Rigid PVC Compounds: impact modifiers
In the field of plastic materials, general-purpose rigid polyvinyl chloride (PVC) compounds have become an indispensable key material in industrial production due to their unique properties and wide applicability. This compound has both rigidity and medium impact resistance, and the realization of this excellent property is inseparable from PVC impact modifiers.
As the core additive of PVC materials, it significantly improves the toughness of the material while maintaining the rigidity of the material by physically or chemically cross-linking with the molecular chain of the PVC matrix.
This enables general-purpose rigid PVC compounds to maintain structural stability while effectively resisting external impacts such as collision and extrusion, greatly reducing the risk of material damage, and providing reliable quality assurance for downstream applications.
1. Perfect adaptation of impact modifiers and profile extrusion
In terms of processing and use, general-purpose hard PVC materials are particularly suitable for profile extrusion. It works particularly well with extrusion machines and production processes.
When producing profiles, adding impact modifiers to PVC will not only not affect the fluidity and shaping effect of the material, but will make the molecular structure of the material better. In this way, the materials are mixed more evenly under high temperature and high pressure, can pass through the mold more smoothly, and the profiles made are more accurate in size, smoother in surface, and the quality is top-notch in the industry.
In addition, hard PVC itself has good heat resistance, and with the help of impact modifiers, it can prevent the material from decomposing and discoloring during the extrusion process, ensuring stable product quality. This can not only increase production speed, but also reduce unqualified products, bringing real benefits to the factory.
2. Construction field: safety and beauty under performance blessing
In the construction industry, general-purpose hard plastics (rigid PVC compounds) are particularly used, and door and window materials are its "main battlefield". We add an anti-impact additive to the plastic, and the finished doors and windows are usually not afraid of bumps, wind and rain, are not easy to deform and damage, and can be used for many years.
Through special machine extrusion molding, the size and shape of doors and windows can be made very accurately, and they are tightly sealed after closing the doors and windows, which are heat-insulating in summer and warm in winter.
They are particularly comfortable to live in and save electricity. If there is bad weather such as strong winds and hail, the doors and windows can withstand it better because of the anti-impact additives.
In addition to doors and windows, products such as architectural decorative lines and wall panels are also particularly suitable for this hard plastic.
It has a hard texture, and the decorative lines and wall panels made of it are not easy to collapse and deform, and they look neat and beautiful when installed on the house.
And because of its anti-impact properties, you don’t have to worry about damaging the product whether it is moved during transportation or knocked during installation.
3. Pipeline manufacturing: dual performance guarantees system stability
In the production of pipelines, general-purpose hard PVC materials are very useful. The common drainage pipes, sewage pipes, and some water pipes in our lives are made of this material through extrusion molding.
Why choose it? First of all, the water pipe must be hard enough to withstand the pressure of the water flow inside and the squeezing of the soil outside. PVC with impact-resistant additives has just the right impact resistance. Whether it is digging a pit to bury the pipe during construction or the ground collapses in the future, it is not easy to crack or crush the pipe, which can make the water pipe last longer.
In addition, hard PVC itself is corrosion-resistant. With the impact-resistant additives, even if there are corrosive substances such as acids and alkalis in the surrounding environment, or the ground is deformed due to temperature changes, the water pipe is not afraid of corrosion or damage, and can be used very stably in various complex environments.
Fourth, furniture and industrial equipment: reliable application in multiple scenarios
In the field of furniture and industrial equipment, the application of general-purpose hard PVC materials is becoming more and more extensive.
When making furniture, hard PVC materials are particularly suitable for places such as table legs and chair frames. It is hard enough to support the weight of the furniture steadily; after adding impact-resistant additives, the furniture is not easy to be damaged by accident. For example, the tables and chairs that are often moved around at home are not easy to crack or break even if they are bumped.
On industrial equipment, parts such as machine shields and shells are extruded with hard PVC materials, which can not only protect the equipment, but also are much lighter than metal materials, making installation and transportation easier.
Moreover, the surface of this material is very smooth, so it can be cleaned by wiping it clean when it is dirty. In addition, it has the advantage of impact resistance, so even if the equipment is used in a relatively harsh environment, there is no need to worry about easy damage, which makes it particularly worry-free to use.
With the continuous advancement of science and technology and the increasing diversification of market demand, the synergistic application of general-purpose, rigid polyvinyl chloride (PVC) compounds and PVC impact modifiers will be applied and expanded in more fields due to their stable medium impact resistance and excellent profile extrusion processing adaptability.
In the future, through the optimization of the impact modifier formula and the improvement of the process of combining with PVC compounds, it is expected that more high-performance and multi-functional profile products will be developed to provide better material support for the development of various industries.
