PVC is one of the world's most versatile plastics due to its ability to be formulated to acquire different physical and mechanical properties. For this reason, it has found application in diverse industries and is considered one of the most widely used plastics in the world. It is widely used in the construction industry because it is a relatively inexpensive material compared to other plastics, and it is also an excellent flame retardant.
By its nature, PVC resin is a fine, porous, colorless, and odorless powder that, on its own, has no use. It requires the additives that we at Chemical Additives of Mexico offer to manufacture a specific finished product. There are functional additives that aid in the processing of PVC and others that impart specific properties to the finished product. These are incorporated into the resin through a mixing process involving high speeds and temperatures.
Our experience has taught us that polyvinyl chloride (PVC) is a complex polymer to formulate, requiring significant technical knowledge to understand the interaction between all the variables involved. Among its advantages is the ability to change its physical properties to make it a very flexible or rigid plastic, depending on the needs of the product being manufactured.
One of our sales technicians will contact you to find out in general what material you produce and your specific requirements.
If your company currently uses any PVC additives, we'll check our product portfolio and send you information if we have a similar product. If we believe you need something new, we'll make a recommendation.
If so, a sample is offered and the option of providing on-site technical advice on your manufacturing process.
If you are just starting to produce PVC, we would be happy to assist you.
A sample is offered, along with the option of providing on-site technical advice during your manufacturing process.
There are three different PVC processing methods, each with its own variations: extrusion, injection molding, and calendering. Depending on the process and established conditions, the formulator must carefully select the set of additives that will ensure a proper finished product. We invite you to consult with one of our technicians regarding this matter.
This parameter is necessary to determine the degree of flexibility your product requires to meet its final specifications and ensure smooth processing. Highly flexible grades are available for hoses (Shore A), semi-rigid grades for injection-molded parts, and rigid grades for gutters or PVC pipes (Shore D).
It's important to recognize the lifespan your company will offer your products. This property is what allows PVC to retain its mechanical properties through the refraction and dissipation of sunlight. Our UV protectors are also compatible with polyethylene, polypropylene, polyurethane, and other plastics.
A product's density directly impacts its appearance, cost, and processing. It also significantly affects its physical and mechanical properties, making it crucial to identify the type of mineral filler that will be added to the PVC.
This property is associated with rigid PVC, and it is available in both opaque and transparent grades. It is typically used in rigid containers and profiles. The most common grades are acrylic- and butadiene-based, which allow for energy dissipation throughout the polyvinyl chloride (PVC) matrix.
An important property for maintaining productivity in your process and preventing surface defects and/or thermal degradation. It is important to pay attention to the lubrication system to achieve the correct balance between the lubricants chosen for its formula.
Other properties to consider include resistance to flammability, extraction by chemical attack, low smoke emission, low whitening when folded, demolding, low blocking, good cling or adhesion, among other aspects.
