ACCUREL® DS 310 is a highly loaded “dry silane” concentrate based on LLDPE and AMEO (3-Aminopropyltriethoxysilane). It is bifunctional, possessing a reactive primary amino group and hydrolysable ethoxy silyl groups.
Typical Applications
The dual nature of the dry silane concentrate ACCUREL® DS 310, allows the chemical binding of inorganic materials (e.g. glass, metals, fillers) with organic polymers (e.g. thermosets, thermoplastics, elastomers) functioning as an adhesion promotor, crosslinker and/or surface modifier.
Benefits at a glance
ACCUREL® DS 310 is used in thermoplastic applications to improve:
In the presents of humidity, the ethoxy groups of ACCUREL® DS 310 can hydrolyze to form reactive silanol groups, which can bond to a variety of organic groups or on inorganic fillers. Upon hydrolysis ethanol is released.
The organophilic amino end can react with suitable polymers.The curing of the alkoxy groups depends on time, temperature and thickness of the parts and the available moisture. To enhance the bonding due to hydrolysis, catalysts like organo metal components like DBTL can be added separately. ACCUREL® DS 310 may be used with such polymers as epoxy, phenolic, furan and melamine resins, PA, PBT, PC, ECA, PP, PVB, PVAC, PVC, PS, nitrile rubber, polyesters, acrylates and silicones.
- The embedding of fillers for highly filled compounds with inorganic or carbon-based materials to achieve high thermal conductivity
- The embedding of flame retardants, like ATH or MDH especially in HFFR compounds
- The adhesion on solid inorganic surfaces especially glass, glass fibers, mineral wool, silica, quartz, wollastonite, mica etc.
- The heat distortion temperature and hot set performance of various polymers and cable compounds
- Mechanical properties, such as flexural strength, tensile strength, impact strength and modulus of elasticity
- Moisture and corrosion resistance
- Electrical properties, for example CTI value or dielectric constant, volume resistivity
