- What does it do?
During the compounding/plasticizing process, the addition of 2-5% (weight) Booster EP reduces the size of the individual “minority components” in the blend, enabling a better dispersion of those components in the dominant matrix. By reducing the size of the minority components, its intrinsic surface is increased, resulting in a larger contact surface with better bonding behavior.
Features & Benefits

Blending (slightly contaminated) PS scrap with (virgin or recycle) HIPS to get a high quality MIPS Low cost recycling of metallized polycarbonate scrap Reprocessing PET bottle scrap (if applicable: incl. PP ring) to a thermoforming-friendly sheet or film.
Applications & Uses
- Compatible Polymers & Resins
- Plastics & Elastomers Processing Methods
- Use
- Alloying agent for polymer/ elastomer blends
- Carrier for masterbatch
- Directions for Use
Alloying agent: Quantity needed: 3-5% of weight of final mixture. In order to optimize the reactivity of Booster EP it is recommended to set the temperature in the first zone (near the hopper) at 200-225°C. Pre-compounding Booster EP might permit to achieve better results.
Carrier for Masterbatches: Quantity needed: 3-5% depending of the composition Specific directions for any class of polymers may be obtained from to the technical department.
- Characteristics
Physical characteristics
- Improved impact strength
- Improved tensile strength and elongation properties
- Improved E-modulus
- Better dispersion of additives (color masterbatch, stabilizers, flame retardants etc.)
- Fine dispersion of non-thermoplastic materials (aluminum coating etc.)
Processing characteristics
- A better dispersed polymer blend processes easier and faster, without any strand breaks reduction/elimination of de-lamination effects non-thermoplastic components (e.g. metallic coatings on CD-s) are invisibly dispersed in the polymer, allowing for a broad range of applications
- Examples of Applications
- Recycling CD scrap into a reproducible high heat ABS/PC-ABS characteristic material
- Recycling HIPS scrap into MIPS for film and sheet
- Recycling PET bottles with PP cap-rings into a high quality, high impact
- PET resin
