4 birds with one stone. This is exactly what you can achieve with your compound by adding 0.3-0.5% of a titanate or zirconate. The high-performance additive causes a nano-fine distribution of your filler or pigment. You profit several times over:
- Filler contents up to 80%
- Improved mechanical and optical properties
- Flame retardancy
- Cost savings
As a long-standing partner of Kenrich Petrochemicals, Inc. (https://4kenrich.com), we incorporate your needs into the latest developments and keep our finger on the pulse with our innovations.
Silanes are very often used for the coupling of filler and polymer. However, the application possibilities are very limited (e.g. ATH, MDH).
Our solution: Use a titanate or zirconate! In this way you can perfectly disperse all kinds of fillers (also lime, carbon black, Kevlar, etc.). Our solution: Use a titanate or zirconate! In this way you can perfectly disperse all kinds of fillers (also lime, carbon black, Kevlar, etc.). You get the possibility to increase the filler content up to 70-80%. This not only saves costs, but you also benefit from improved mechanical properties, a flame-retardant finish and favourable processing conditions.
With titanates and zirconates, it is possible to coat fillers and pigments with a nano-sized layer. This enables you to achieve perfect dispersion of your mineral and non-mineral fillers. The result is a compound with excellent mechanical and optical properties, optimal integration of the fillers into the polymer and the possibility of filling compounds with up to 80%. At the same time, the viscosity remains very low. The speed of extrusion can be accelerated by up to 40%. And when using a phosphonate titanate, you even achieve flame-retardant, self-extinguishing properties.
Application examples of titanates / zirconates in filled compounds
A comparison of the mechanical properties of an unfilled and a PP compound filled with 50% ATH shows impressive effects. As a “coupling agent”, 0.5% of our titanate Ken-React® 38S was used:
- Tensile strength: +10%
- Modulus of elasticity: +40%
- Elongation at break: +35%
A PP compound filled with 70% CaCO3 (3µ) and treated with 0.5% of the titanate Ken-React® TTS still shows very high elasticity (180° bending):
An LDPE compound filled with 44% CaCO3 and treated with 3% of the phosphato-titanate Ken-React® LICA 38 shows the intumescent flame retardant effect:
An untreated LDPE compound filled with 44% CaCO3 was used as a reference.
Titanates and zirconates are suitable for use in filled compounds and are characterised by the following properties:
- Compounds with very high filler content
- Perfect dispersion
- Significantly improved mechanical and optical properties
- Non-halogenated flame retardant
- Process and cost advantages due to reduced viscosity
- Increased productivity
- Cost advantages due to lower polymer use
With titanates and zirconates as highly effective additives in compounds, significant and innovative improvements can be achieved that have a decisive influence on your competitiveness. The advantages are of a technical and economic nature.
