Tosaf Sustainability

Smoothing the way for recycled plastic

The integration of recycled and recyclable materials into plastic goods is a key step towards achieving a healthier approach to the environment. But, working with these materials presents many challenges, from reduced melt flow in processing to bad odor in the end product. Tosaf developed a range of additives that help our customers overcome these challenges, while adding value to the final product.

Odor Scavenger

Our odor scavenger masterbatch absorbs and eliminates the rancid odors that develop in recycled materials throughout storage and processing, enabling plastic convertors to successfully use low-cost, environmentally friendly raw materials to create a vast range of consumer products. Particularly helpful in the production of food packaging, such as beverage bottles, caps and closures, our odor scavenger is also useful for materials with strict and challenging organoleptic and/or VOC demands.

Highlights
  • Absorbs and eliminates malodors during the production process and in the end product
  • Stabilizes virgin or recycled material against further thermal degradation
  • Suitable for use with any polyolefin

Flow Enhancer (CRPP) MB

Our polypropylene flow enhancer masterbatch improves the processability of recycled raw materials, contributing to faster mold-fill rates and shorter overall cycle, without compromising mechanical properties or costs.

Highlights
  • Improves flow characteristics of recycled and prime polypropylene
  • Safe to handle, transport and store – does not require any special safety measures
  • Complies with food contact regulations

Boosters for the recycling industry

Our polypropylene flow enhancer masterbatch improves the processability of recycled raw materials, contributing to faster mold-fill rates and shorter overall cycle, without compromising mechanical properties or costs.

Highlights
  • Improves flow characteristics of recycled and prime polypropylene
  • Safe to handle, transport and store – does not require any special safety measures
  • Complies with food contact regulations

o optimize the recycling of plastic products, every element must be both recyclable and suited to recycling in the standard recycling processes. Our recyclable additives fit the bill, while retaining their high performance. In this way, we enable you to produce high-quality, fully-recyclable products, at no extra cost.

Near IR (NIR) Detectable Black MB

Carbon black pigment provides excellent color strength and scattering quality, but it completely absorbs the near-IR (NIR) radiation used in recycling plants to detect and sort plastics. As a result, huge volumes of plastic in applications like ready-made meal boxes is sent to landfill instead of being recycled. Our IR detectable black offers strong black color, without compromising detection during the sorting process, ensuring that products are fully recyclable.

Highlights
  • Fully detectable by NIR sorting devices
  • Completely recyclable
  • Strong, jet-black shade

Clarifying Agent for PP

There is a global trend to replace multi-layer films made from different materials with mono-material films that have superior mechanical and optical properties. These films guarantee good sortability in waste separation. Our clarifying agent helps polypropylene producers and converters stay ahead of trends in packaging, appliances, medical, houseware and food storage, achieving unprecedented transparency while benefiting from significant energy savings and faster production in injection molding.

Highlights
  • Energy efficient
  • Complies with food contact regulations
  • Faster production in injection molding

Matte for PE

Our recyclable matte additive is the environmentally-conscious alternative to matte coatings. Delivering a premium chic look and feel, it offers excellent brightness in light transition with no transparencies. Suitable for polyethylene films, it requires no additional converting processes, can be used for thin skin layers (5-7 microns) and provides superb haze (~80%) at a very low gloss (<10). To make select areas of the matte transparent, simply apply a lacquer coating or glue a clear stamp on top of the matte layer.

Highlights
  • No fillers – based on polymer mixture
  • Versatile – suitable for polyethyleneand polypropylene -oriented films
  • Processing – excellent rheology, low dye buildup

Non-Halogen Flame Retardant Additives

Our family of flame retardant additive masterbatches uses non-halogen additives that are not harmful to the environment and can be recycled. Using premium-quality active ingredients and innovative formulations, we help customers to achieve high-level product performance, while supporting resource efficiency and environmental protection. This solution enables manufacturers in the electrical & electronics and home appliance industries to produce products that meet the WEEE (Waste of Electric and Electronic Equipment) standard, by replacing the hazardous substances in their products with a safer alternative.

Highlights
  • Suitable for recycling
  • Thermal and chemical stability
  • Minimal effect on the production process
  •  

In light of growing consumer concern for the environment on a global scale, there is increasing regulatory and market demand for manufacturers to use biodegradable and compostable polymers. Our standard and custom-made color masterbatches and compounds are compatible with all biodegradable carriers, including PLA, PHA/PHB, PBS and PBAT. They also offer the added value of enhanced performance, properties, processability and resin stability. Our solutions support a wide range of applications – flexible and rigid, durable and disposable, transparent and opaque.
All the components, pigments and additives in our biodegradable masterbatches are certified according to current regulatory requirements, including EN 13432, ASTM D6400 and more.
