COLOURS FOR PU FLEXIBLE FOAM

BLACKS AND COLOURS

REPI liquid colours for FLEXIBLE FOAM are high performance pigment and carbon black dispersions specifically formulated for the colouration of flexible, rigid and semi-rigid polyurethane foams in addition to high resilience and slowrecovery foam.
Suitable for polyether and / or polyester PU systems, these low viscosity liquid colours are particularly resistant to high temperatures developed during the reaction stage, thus fully respecting the cellular structure and the physical properties of the foam.

ADDITIVES FOR RECYCLING

Specialty additives to improve recyclability of PET: 
1) ANTI YELLOW range: different additives to correct the off-shade of r-PET which can be yellowish-greyish-greenish-reddish. 
these additives are able to create greater uniformity of shade of r-PET resin or r-PET final product, improving therefore aesthetics of r-PET resin or r-PET final product.
Depending on the specific product, the anti yellow additives reduce the yellow index ("b" of Lab) - stabilise the grey shade ("L" of Lab) - balance the green shade ("a" of Lab)
2) IV ENHANCER additive: it enhances the physical and mechanical characteristics of r-PET by extending the PET chain. IV increases from 0,05 dl/g to over 0,10 dl/g depending on the LDR. the additive is no-cross link , this means that molecular weight (MW) and mechanical properties increase accordingly
3) OPTICAL BRIGHTNERS: these additives increase brightness of r-PET avoinding the "L" of Lab  to drop.

BLOWING ADDITIVES

REMAP Blowing Additives have been specifically designed to give enhanced characteristics during the blow moulding process. The different formulations allow the PET preform to be homogeneously reheated, due to better infrared absorption.

These additives provide lower blowing energy costs and reduced percentage of scraps, especially for thicker preforms, while leaving productivity unaltered when not even increased.
Remap BA additives can be used as alternatives to fast re-heat resins.
 
KEY FEATURES
• Improve heat absorption
• Energy saving (5-15% depending on preform design and weight, and on blowing machine settings)
• Improve productivity
• Reduce scraps
• Low viscosity liquid
• Let down ratio: 0,02 – 0,05%
• Meet EU and FDA food contact regulations

ANTISTATIC AGENTS

REPI ANTISTATIC ADDITIVES are medium polarity ionic liquids specifically tailored to improve conductivity properties of microcellular polyurethanes.
They are particularly suitable for electrical resistance reduction in footwear and C.A.S.E. applications.
REPI ANTISTATIC ADDITIVES can be used as component in the polyol formulation or can be fed in a separate stream directly into the mixing head.

BENEFITS
 
• Excellent electrical conductivity
• Optimal thermal, mechanical and electrochemical stability
• Exceptional dissolution properties
• Compatible with polyether and polyester PU systems
• Easy blending with polyol
• Low viscosity

 TYPICAL PROPERTIES

FUME' COLOUR RANGE FOR RECYCLED PACKAGING

COLOURS CAN BE OF GREAT HELP WHEN DEALING WITH RECYCLED POLYMERS IN PACKAGING.
Besides additives, colours also can be of help. We know that the trend is to reduce colours, or even to go clear, but… many brands are not ready to sacrifice aesthetics of their packaging and their brand recognition. When a very dark r-PET is used, the sole Anti Yellow additive may not be enough. For this, REPI has developed the “Smoky or Fumè” colour range, some proposals of different shades which would be able to even give the packaging a “premium and elegant look”, masking a bit the R-pet visual influence and at the same time adding value to it. Those shades have in common a “dirty” effect and are dosed at so low dosages (as low as 0,05%) that do not impact in the recycling stream, since they are detected as transparent light colours. The range goes from a light amber to light blues, greys, aqua-marine shades and even antique rose, which often are chosen after an evaluation of the starting r-PET look. We are receiving real interest from Brand Owners, since the Smoky-range represents the answer to their concerns related to aesthetics when adding recycled material and also, they get the opportunity to reduce the amount of colour, but without removing it out completely.

UV STABILIZERS

UV radiation is one of the causes of alteration in taste, smell, colour and biological characteristics of products packed in PET.
Many products contain light sensitive ingredients and PET alone cannot protect them from degradation. Several grades of REMAP UV ABSORBERS are available to cover the different protection requirements according to final product needs; this enables the customer to select the proper additive, optimising the cost/ benefit ratio.
REMAP UV ABSORBERS capture UV radiation from 300 to 400 nm, creating different levels of protection, depending on the LDR and the packaging wall thickness.

KEY FEATURES 
• UV radiation absorption: 300-400 nm
• Low viscosity liquid
• No influence on the natural transparency
• Let down ratio: 0,05 – 0,20%
• Meet EU and FDA food contact regulations

DOSING UNIT OF LIQUID COLOURS AND ADDITIVES

The U2011 dosing unit family is the latest development among the REPI electronically controlled dosing systems for thermoplastic applications.

Suitable for injection moulding machines as well as extruders, it is normally fitted with gear pumps ranging from 0,06cc to 10cc. (other sizes available upon request), which ensure high precision and constant dosage of colours or additives. The unit gets the input signal from the machine, thus adapting to the output possible fluctuations, in order to maintain the same dosage throughout the production. The metered quantity can be checked in real time on the unit screen and adjusted if required, while the machine is in motion. The amount of colour in the service drum is constantly checked, and a minimum level can be set at which the unit gives an alarm, allowing the operator to refill the drum.

LIGHT METER: PREFORM COLOUR CONSISTENCY CONTROL

Most beverages need special protection from visible light, in order to maintain their sensorial and nutritional characteristics. in food packaging applications, such protection is often obtained by using colours, which are dosed at different addition rates. One of the best ways to ensure that the final container will have the necessary light protection is to measure light transmission directly on the PET preform, before it passes to the blowing stage.

The colour amount level in the preform is tested by spectrophotometer techniques or, very often, just by visual control. The first approach is expensive, requires lab skills and often yields more data than needed. Moreover, it is difficult to apply to opaque preforms.
Visual checking is a standard practice for checking preforms on the shop floor, but there is a limitation with opaque preforms and the reliability of the result depends a lot on the operators’ experience.
Light Meter measures all opaque, semi-transparent and transparent preforms, offering a more scientific alternative to visual control for all coloured preform ranges.
Depending on preform opacity and on the purpose of the control, different options are available:
• Flash
• RGB
• RGB-UvIR (for standard and XL preforms)
• Light Meter Plus
