Product Series

PEARLTHANE stands for a range of high performance TPU resins intended for extrusion and injection moulding markets. Each range of products is carefully designed and optimized to excel in a specific field of applications.

Series 11H

High performance extrusion/injection moulding grades based on newest Merquinsa’s technology; 11H grades exhibit higher crystallinity, faster processing, outstanding mechanical properties and improved chemical resistance. Also offers other benefits such as Low density or high fluidity grades which help you to reduce costs.

Series 11T

The 11T series offers outstanding abrasion and wear resistance and a fast setup in the mould. The 11T series outperforms conventional adipate ester based TPUs in hydrolysis resistance and low temperature flexibility, as well as adhesion strength to other polar plastics such as ABS, PA and PVC.

Series 12C

This family of low melting polyester based TPUs is currently being developed for a wide range of speciality engineering plastics compounds. The special thermal and rheological properties of this series provides enhanced compatibility with a wide variety of other thermoplastics.

Series 12F

Based on Merquinsa´s expertise in both high-melting film grade TPUs and adhesive and coating applications, this new series is especially being designed for the adhesive film markets in which film quality and outstanding adhesion performance are the key properties.

Series 12K

This unique range of polyester based TPUs consists of a very clear, gel free, low color and easy to extrude film range of both high and medium melting range. All grades of this family are FDA approved products. Specific high tack grades are also available in film grade quality.

Series 15N

This family consists of a unique series of TPU grades based on polyether copolymers offering excellent hydrolysis resistance in combination with good heat resistance and mechanical properties. Additionally, the 15N series excels for its outstanding low temperature performance and elastic properties.

See also: Success Story Pearlthane 15N85 & Literature "Technological Advantages of Polyether Copolymer based TPUs"

Series 16N

The polyether based TPUs are used when extreme good hydrolysis and microbial resistance are required, e.g. in underground applications such as certain cables. The polyether range complies with FDA regulations.

Series 18VT

Special Polyether family based TPU featuring high moisture vapour transmission (HMVT), outstanding wear resistance and excellent blown/flat film processing. This family’s grades also offer the desired hydrolysis and microbe protection.

Series 91T

This series is an aliphatic specialty TPU for injection moulding. It offers non yellowing properties which make it the material of choice for light colours in interior automotive and sport & leisure applications.


Series 95N

Aliphatic polyether copolymer-based TPU represents 95N grades offering full UV resistance, good mechanical properties, as well as improved hydrolysis resistance compared to Series 11T & Series 11H based on polyester TPU. When series 95N is overmoulded into other polar polymers such as ABS, PC or PA, the result is a perfect combination of elasticity, UV protection and abrasion resistance with a wide range of applications.

 

 

Melting Range Overview

In the figure below, Merquinsa´s range is depicted on the melting temperature scale.

For more information, please consult us.

 

 

Hydrolysis Resistance

In the picture below, the hydrolysis resistance (immersion test in distilled water at 80ºC) is presented for the 85 Shore A grades of the different PEARLTHANE families.

 

 

Heat Resistance

The unique copolymer family also features an improved heat resistance in comparison to polyethers as illustrated in the Figure. The graph shows the half life time (time needed to reduce the sample's tensile strength with 50%) versus the test temperature.

 

 

Low Temperature Flexibility

One of the most important feautures of TPUs is their excellent low temperature flexibility. In the figure below, the differences between the described product families are depicted in terms of glass transition temperatures.

 

 

Product Series' comparative table

A qualitative comparison of the Series 12K, 15N and 16N is presented below for a selection of properties. Please notice the differences in microbe and hydrolysis resistance as well as heat ageing.

Colouring

PEARLTHANE is only supplied in its natural color which would be somewhere between transparent yellow and opaque white depending on the grades.

However, PEARLTHANE can be coloured easily via masterbatches.

Merquinsa would recommend TPU masterbatches with PEARLTHANE and PEARLCOAT as the carrier materials.

Masterbatches based on polyethylene, polypropylene or PVC are not suitable.

For more information, please consult us.
