Impact Modifier - Polymer additive on basis of nano technology*
The patent covers an innovative process to obtain a nano-structure of polyurethane in a reactive diluent. This improves the physical properties of plastic materials, such as transparency, impact strength, pull-out and shear strength.
According to a recent Frost & Sullivan study, the European market volume for Emulsion Polymers in 2007 was 3.8 bn EUR, growing to 4.2 bn EUR in 2010. Although this material can be considered an "additive", it can actually comprise more than 50 percent of the final reactive diluent, so it can capture a significant share of that market. This assumption is further reinforced by the fact that the cost of this additive is not far above the polymers it is added to. Thus, using it does not need to impact the final price significantly. The technology can be adapted to various applications via a building block strategy. The vendor can adjust the combination of polymers to accommodate various customer requirements. Thus, the final product can still maintain the same desired characteristics that it already currently has, while improving other important characteristics such as transparency, flexibility and aging.
This invention can be used to improve properties of a wide range of materials such as polymers, adhesives, coatings, glues, lacquers, etc. Therefore this invention has the potential of expanding the use of the materials it goes into beyond current market expectations.
- Nano structure
- Polyurethane
- Polymer additive
- Impact strength
- Transparent polymers
- Reactive diluent
- The new polymer additive based on nano technology is added to the reactive diluents where a nano structure is formed in the polymers which causes
- an increase of transparency and
- an improved impact strength, scratch resistance as well as pullout and shear strength
- minimised aging of the polymers
- that the polymers are less brittle (especially when mineral flame retardants are used) - The technology can be adapted to various applications via building block strategy
- A low cost standard polymer (polyurethane) is used for the nano particles
- The mixture of the additive and the reactive diluent are stable and can be stored for several months before polymerisation
- Polymers
- Adhesive
- Coatings
- Lacquers
