Masterbatches, Concentrates and Colorants for Polymers

Black Masterbatch 40% MW-PE100

admin — Wed, 24 Feb 2021 15:57:33 +0000

Description

A premium masterbatch developed specifically for pressure water supply pipes and polyethylene gas pipes. The masterbatch contains high-purity P-type carbon black, which provides the highest specific pigment surface area and, consequently, the highest tinting strength (up to 120%). P-type carbon black has a very low content of ash (less than 0.1%), sulfur and extractables, so this grade is approved for use in products in contact with food and in water supply pipes. Only virgin polyethylene is used as the polymer matrix, and the processing additives (stabilizer, processing aid) meet FDA requirements and are more stable in terms of migration.

Black masterbatch 40% MW-PE100 features improved carbon black distribution, reduced moisture absorption and high physical and mechanical properties, and pipes based on it meet the requirements of international regulatory documents.

Key advantages:

highest tinting strength
compliance with PE100 standards when coloring the corresponding polyethylene grades
low ash residue
low moisture absorption of the compound
improved dispersibility
high UV resistance
heat resistance
food contact approval

Masterbatch for Polyamides MW-PA CB10

admin — Wed, 17 Feb 2021 18:54:33 +0000

Description

The concentrate is based on polyamide and is intended for efficient coloring of injection molding polyamides 6, 66 and compounds based on them without reducing mechanical properties. The concentrate contains no polyolefins, which ensures high mechanical performance of parts, better adhesion in two-component molding, a substantial increase in UV resistance, improved laser marking, and fewer static electricity problems. The pigment is an ultra-fine, ultra-pure premium-grade carbon black. The polymer carrier ensures excellent homogeneous pigment distribution in the colored polymer and has a positive effect on polyamide performance.

Key characteristics of the MW PA CB10 masterbatch for polyamides include:

excellent compatibility with polyamides
no negative impact on properties
premium carbon black
a unique polyamide carrier that improves the properties of the colored resin
formulation can be adapted
innovation and a competitive advantage

Material Wizard’s deep expertise in polyamides has allowed us to surpass in quality even globally recognized masterbatch producers, who due to their specialization do not address a number of highly specific issues characteristic of polyamide products.

White masterbatch for films TiO₂ 70%

admin — Wed, 16 Dec 2020 21:22:56 +0000

Description

High-loading white masterbatch based on rutile TiO₂ — 70% active pigment in a polyethylene carrier matrix, with no fillers. A premium grade for thin packaging films (15-40 µm) where maximum opacity is required at a minimum dosage (1.5-3.5%). High pigment purity and optimal particle size ensure rich whiteness without reducing film strength. An analogue of the Tosaf WPE71 series and Schulman Polybatch P8555 for high-loading white MB.

Key properties

TiO₂ concentration 70% in a PE carrier — no CaCO₃ or other fillers
Minimum dosage 1.5-3.5% — low let-down ratios
High opacity on thin films of 15-40 µm
No reduction in film strength thanks to high pigment purity
Good dispersion — suitable for blown and cast extrusion
Stable processing over a wide temperature window

Applications

Thin packaging films. Hygiene packaging, dairy product bags, shrink film, snack packaging — wherever maximum opacity is needed at minimum thickness.

Multilayer food contact films. White layer in 3/5/7-layer coex films for packaging dairy, meat and frozen products. Compliance with Regulation (EU) 10/2011 for plastic packaging — per separate batch specification.

Premixes for compounders. A cost-effective way to add TiO₂ to PE, PP and PA compounds — dust-free with accurate dosing.

Lamination film. White layers of laminated structures (BOPP, BOPET) for printed labels.

Regulatory notes

TiO₂ as food additive E171 has been banned in the EU since 7 August 2022 (Regulation (EU) 2022/63). The restriction applies to food products, not packaging films. The use of TiO₂ as a pigment in plastic packaging remains permitted under Regulation (EU) 10/2011, subject to the Specific Migration Limit. For food contact applications, request a Declaration of Compliance (DoC).

White Masterbatch for Films, TiO₂ 25%

admin — Fri, 04 Dec 2020 09:16:27 +0000

Description

White masterbatch (white concentrate) based on rutile TiO₂ — 25% active pigment with 43% CaCO₃ as a co-active filler in a polyethylene carrier matrix. Designed for the production of packaging, agricultural and technical films by blown or cast (flat-die) extrusion, where stable opacity, rich whiteness and good dispersion without defects (“fish eyes”) are required. Economy grade: 25% TiO₂ + 43% CaCO₃ provides the optimum price/opacity balance for high-volume packaging solutions.

Key properties

TiO₂ concentration 25% + CaCO₃ 43% in a PE carrier
High opacity at a dosage of 3-8% of film weight
Good dispersion — no “fish eyes” on thin films of 20-100 µm
Compatible with LDPE, LLDPE, HDPE, PP — standard blown/cast lines
Economy grade — optimum opacity/price ratio
UV stabilization with an additional UV-MB if required (for agricultural films)

Applications

Packaging films. Polyethylene packaging for food and non-food products (sacks, bags, shrink film). Compliance with 10/2011 (EU food contact for plastic packaging) — per individual batch specification.

Agricultural films. White mulch films, greenhouse films with minimal sunlight transmission, silage films.

Construction films. White films for waterproofing, vapor barriers and temporary covering.

Technical films. Stretch film, banding film, liner materials.

Injection molding. White parts for household appliances, molded packaging — economy grade.

Regulatory notes

TiO₂ as food additive E171 has been banned in the EU since 7 August 2022 (Regulation (EU) 2022/63, based on the 2021 EFSA opinion that a safe daily intake could not be established due to nanoparticle accumulation). This restriction applies to food products, not to packaging films. The use of TiO₂ as a pigment in plastic packaging remains permitted under Regulation (EU) 10/2011, subject to the Specific Migration Limit (SML) for food contact. For food-contact applications, request a Declaration of Compliance (DoC) for the specific product and contact conditions.
