No definitive statements can therefore be made as to type conformity, processability, long-term performance characteristics or other production or application parameters. Therefore, the purchaser/user uses the product entirely at his own risk without having been given any warranty or guarantee and agrees that the supplier shall not be liable for any damage, of whatever nature, arising out of such use. Unless specified to the contrary, the values given have been established on standardised test specimens at room temperature. The figures should be regarded as non-binding approximate data only, and not as guide values or binding minimum values. Please note that, under certain conditions, the properties can be affected to a considerable extent by the design of the mould/die, the processing conditions and the colouring.

[ 1.4 Test values ]

Unless specified to the contrary, the values given have been established on standardised test specimens at room temperature. The figures should be regarded as guide values only and not as binding minimum values. Kindly note that, under certain conditions, the properties can be affected to a considerable extent by the design of the mould/die, the processing conditions and the colouring.

[ 1.5 Test values styrenics ]

Unless specified to the contrary, the values given have been established on standardised test specimens at room temperature. The figures should be regarded as guide values only and not as binding minimum values. Kindly note that, under certain conditions, the properties can be affected to a considerable extent by the design of the mould/die, the processing conditions and the colouring. This is valid especially for CTI.

[ 1.6 Medical products ]

^**Only Bayer plastics which fulfil the test requirements of ISO 10 993-1 may be used for medical articles which come within the scope of this standard. Applications involving long-term contact for which Bayer plastics are not intended are exceptions. However, the biocompatibility tests which we perform according to this standard do not cover the following ranges of application for medical articles manufactured from our material: Long-term use over 30 days, particularly use as (cosmetic or reconstructive) implant Long-term contact over 30 days with endogenous substances (blood, tissue, dentin, other body fluids) Multiple use for medical applications Therefore Bayer plastics should not be used for long-term applications or with long-term contact. Use of recycled material and incompatible additives Our test results for biocompatibility do not apply to the use of recycled materials or the use of other additional material components in the finished product. Responsibility of the manufacturer of the medical article The use of our material outside the above-mentioned test scope of ISO 10 993-1 occurs exclusively on the responsibility of the processor of our material and the manufacturer of the finished product. As regards the production conditions of the processor of our material which are not known to us, it is the responsibility of the processor to ascertain the suitability of our materials in the finished product in terms of directives and statutes to be observed. The suitability of our materials also depends on the ambient conditions (see below) for the finished product. Chemical compatibility, temperature, design of the medical article, method of sterilization, internal stress within the finished article, and external stress all influence suitability, and are therefore the responsibility of the processor and the manufacturer of the finished product. Multiple-use of medical articles Medical articles which are intended for single use and which were manufactured from Bayer plastic are not suitable for multiple use. If the medical article was manufactured for multiple use, it is the responsibility of the manufacturer of the finished product to determine an appropriate number of times it may be used, by determining and evaluating the conditions of sterilization and final use. Appropriate warnings and instructions must be given to the final user. Sterilization The use of various methods of sterilization and the permitted number of sterilization cycles for a medical article which is made from our materials depend on the design of the parts, the processing parameters, the sterilization temperature and the chemical environment. Therefore the manufacturer must determine and evaluate the most suitable method of sterilization (and if applicable the permitted number of sterilization cycles) for each medical article. Appropriate instructions and warnings must be given to the final user.

[ 1.7 Processing note ]

Under the recommended processing conditions small quantities of decomposition product may be given off during processing.To preclude any risk to the health and well-being of the machine operatives, tolerance limits for the work environment must be ensured by the provision of efficient exhaust ventilation and fresh air at the workplace in accordance with the Safety Data Sheet. In order to prevent the partial decomposition of the polymer and the generation of volatile decomposition products, the prescribed processing temperatures should not be substantially exceeded.Since excessively high temperatures are generally the result of operator error or defects in the heating system, special care and controls are essential in these areas.

[ 1.8 Recyclate grades Bayblend ]

Recyclate grade In view of the different origins of post-consumer waste, a wider tolerance band has to be expected than for virgin material. Colors have to be agreed on. Since the Bayblend R grades may contain used materials, they may contain additives. Recyclate grades always comply with the statutory provisions currently in force.

[ 1.9 Emission disclaimer for Novodur ]

By virtue of their composition and production technology, components made of this Novodur grade have a very low level of emission if processed correctly.

[ 1.10 Information for Polycarbonate R grades ]

These grades are homogeneous polycarbonates (PC) based on bisphenol A. They are produced through the extrusion compounding of PC basic recyclate obtained by reprocessing, PC production and processing residues. The percentage content of the individual starting materials can vary, in order to achieve the typical properties set out overleaf. PC R grades can contain a pigment component of a different coloring agent, as a function of the input material used. All PC R grades contain release agents. The PC R GF grades can contain both milled fiber and/or chopped strands. The material properties conditioned by fiber length, such as the tensile modulus, can thus vary as a function of the batch. Each batch undergoes physical mixing subsequent to production. In view of the different origins of the basic recyclate, a broader tolerance range has to be expected in the properties than in virgin material.

[ 1.15 Information for coloring natural-colored products ]

In view of the special composition of this product, when coloring natural-colored products particular care must be taken to ensure that all the coloring agents and ancillary materials used are compatible with polycarbonate. If materials are used that are incompatible with PC, a considerable deterioration must be expected in the mechanical properties, in particular.
