Additionally, laser marking versions are available for beverage promotional campaigns. Download EPSeal Product Guide

TPE compounds for plastic closures using the in shell liner moulding process The EPSeal 800 series was developed for PE and PP closures specially designed for the in shell moulding liner technology. The series includes versions for cold fill, pasteurisation and hot fill beverage treatment systems. This series also includes versions with different rheological values to address the special processing requirements of different lining machine types. An assortment of lubricant packages addresses the spectrum of closure and liner profile designs but all lead to a neutral taste and odour sealant whilst remaining consumer friendly and reliable.

Lifoflex B038/B045 These special TPE grades do have a high bonding to PA6, PA66, PA12 in two component parts. Also to glass fibre reinforced polyamide materials (up to 40% of glass fibre) a high bonding strength can be achieved. Modification of the polyamide with a primer is no longer necessary. The outstanding properties of these TPE compounds, like a high service temperature range, high oil resistance, soft touch surface and high flexibility, offer a wide variety of possible applications. Lifoflex B038/B045 materials are very easy to process in injection molding. The wide processing window results in a lower rate of defective parts and faster cycle times. Properties: Very high bonding strength to PA6, PA66,PA12 (including glass fi bre reinforced polyamide) Wide hardness range, from 25 up to 90 Shore A Very good chemical resistance High oil resistance High service temperature range (-40°C up to +120°C) Easy processing Wide processing window Easy coloring with color masterbatches Sof

Our coloured Mediprene compounds are made from medical grade raw materials only, thereby representing a natural expansion of our Medical TPE product range. The colour masterbatch supplier has been selected with care, ensuring that not only the pigments and carriers are compliant with USP Class VI or corresponding parts of ISO 10993 but also that the masterbatches are manufactured under rigorous controls with regard to traceability, consistency and change control thereby fitting the Mediprene concept at our ISO 13485 accredited facilities. In medical devices and pharmaceutical packaging colour is often used functionally to differentiate products and provide an easy method of identification. The vibrant colours achievable with coloured Mediprene compounds also give brand owners a means of adding value to their products and creating visual appeal. A fully colour compounded TPE gives a perfectly dispersed, consistent colour with a correct and reproducible addition level. Mediprene colou

Overmoulding is a powerful technique that allows the production of finished parts in soft and hard material combinations without trimming or assembly. It offers many design and product advantages, allowing designers to differentiate products while meeting important user and patient demands, including soft-touch and cushioning for greater comfort and non-slip surfaces with improved grip for safety. The 500M Mediprene range bonds very well to polyolefins like polyethylene (PE) and polypropylene PP). However, in several medical applications transparent engineering plastics like ABS, PC, PETG and SMMA (and their blends) are utilised. The Mediprene A2 series has been developed to address demands for medical grade TPEs that bond well to these substrates. Special features Unfilled PVC, silicone & latex free 35 to 65 Shore A Flexibility over broad temperature range Resistant to many fluids used in the healthcare environment Sterilizable with gamma, EtO and steam Production site accredited

Introduction Mediprene BM is a range of thermoplastic elastomers (TPE) optimised for medical blow moulding applications. What is blow moulding? Blow moulding is a manufacturing process that is used to produce hollow parts such as bottles, balloons and bags. The process begins with melting the TPE and forming it into a tube, called a parison. The parison is clamped into a divided mould, the tube is pinched at one end, welding it together and then air is blown into it. The air pressure inflates the TPE out to match the mould cavity. Once the TPE has cooled and hardened the mould opens and the part is ejected. Mediprene BM TPE We have designed the Mediprene BM TPE compounds to have high melt strength, giving time to close the mould around the extruded parison while allowing sufficient stretchability during inflation. They also offer good welding in the pinchoff area of the blow mould. They can easily be coloured and give a smooth surface to the finished part. Applications The TPE can

The Mediprene Oil Free range was developed to address demands for transparent medical TPEs with a minimum of potential extractables and leachables. The Mediprene OF range helps to prevent the possibility of oil migrating or leaching out of the material, a key requirement for medical and healthcare-related devices. They are ideal for sensitive medical applications where transparency is also required. Special features: Minimum of potential extractables & leachables PVC, silicone & latex free Soft-touch appeal 40 to 90 Shore A Transparent & Crystal Clear Grades Anti-kinking Sterilizable with gamma, ethylene oxide (EtO) and steam Excellent sealing & adhesion The Mediprene OF grades are also highly suitable for medical tubing. They have a high level of transparency, allowing for clear visibility of the passage of liquids and anti-kinking properties to ensure the free flow of liquids and gasses through the tubing. We also offer grades which display good damping properties,

The Mediprene 500M range encompasses our original medical TPE grades. They are available in hardnesses from 0 Shore A to 62 Shore D. With translucent and transparent grades, they are also easy to colour. Mediprene grades are sterilizable with gamma, EtO and steam and representative grades have passed cytotoxicity tests according to ISO 10993-5 and biocompatibility tests according to USP Class VI. Mediprene TPEs have proven to be a strong alternative as replacement to PVC; they are completely synthetic and latex free thereby minimizing allergy risks. The right TPE formulation is the key to a safe and successful medical product. When a standard formulation does not meet the needs of a unique application, we will formulate a custom solution. Special Features Flexibility and elasticity 0 Shore A to 62 Shore D Transparent and crystal clear grades Soft-touch appeal Excellent resistance to many fluids used in the healthcare environment PVC, silicone & latex free Adhesion to PP or PE i

We have developed a range of Mediprene thermoplastic elastomers (TPE) for plunger seals in single-use syringes. The TPE seal, which is mounted on the end of the plunger, needs to provide a leakproof seal with the syringe barrel. As ease of use for the medical practitioner and patient comfort are also key requirements, the seal helps to optimize plunger movement for accurate dosage control and ease of injection. Originating from medical raw materials with high biocompatibility status and compounded under clean conditions, Mediprene TPEs are the material of choice for medical customers who want to maximize the probability that their devices will pass relevant medical tests. The raw materials in these compounds comply with food contact norms like FDA 21CFR and Commission Regulation (EU) No 10/2011. All polymers used have passed tests according to USP class VI and the paraffinic oil has passed the USP Mineral Oil NSF H1, reg 125038 and also the European Pharmacopeia, liquid paraffin. Fo

Representative Mediprene grades have been sterilized via: Ethylene oxide (EtO) Gamma Irradiation Steam / Autoclave Test Specimens for tensile tests were punched out of injection-moulded plaques. All mechanical test values refer to tensile testing of the material parallel with the flow direction. Changes reported have been calculated by comparing values for sterilized specimens with the corresponding values for the unsterilized reference. A guide detailing the test results is available to download here Investigation shows that EtO is the most gentle sterilization method for Mediprene TPEs.
