By Liesl K. Massey

This widely up-to-date moment variation was once created for scientific machine, scientific packaging, and foodstuff packaging layout engineers, fabric product technical help, and research/development team of workers. This finished databook includes very important features and houses information at the results of sterilization equipment on plastics and elastomers. It presents a prepared reference for evaluating fabrics within the similar kin in addition to fabrics in numerous households. facts is gifted on forty three significant plastic and elastomer packaging fabrics, together with biodegradable or natural polymers. New to this version are resin chapters containing textual precis details together with: class; normal description; purposes; resistances to specific sterilization equipment; and regulatory prestige concerns to be used in clinical units and medical/food packaging. The resin bankruptcy fabric provider alternate identify product facts is gifted in graphical and tabular layout, with effects normalized to SI devices, preserving the favourite structure of the easiest promoting first version and permitting effortless comparability among fabrics and try stipulations.

19] ACRYLONITRILE-BUTADIENE-STYRENE (ABS) Electron Beam Radiation Resistance: E-beam radiation will generally cause a decrease in the impact strength of ABS. 0 megarad of beam radiation. The Izod impact values (ASTM D256) showed linear decrease with increasing dose level. 0 megarad, it lost 5–10% of its original impact value. There was no measurable change in tensile modulus, and an increase in tensile stress at yield of 10 %to 18% was noted (ASTM D638). There was a 5% to 15% difference in tensile stress at fail between the control and irradiated samples.

15] As a rule, the sterilization total dose should not exceed 2 megarad. [16] Sterilization Data by Material Supplier Trade Name: See Tables 1-01 and 1-02. Sterile Applications: Medical devices Table 1-01. 2 ASTM D638 18 EFFECT OF STERILIZATION METHODS ON PLASTICS AND ELASTOMERS Table 1-02. 2 — COLOR PROPERTIES Chapter 2 Acrylonitrile-Butadiene-Styrene (ABS) Category: Engineering thermoplastic, styrenics. General Description: Acrylonitrile-butadiene-styrene (ABS) includes a range of resins, each manufactured with usually more than 50% styrene and varying amounts of acrylonitrile and butadiene.

0%. 5 megarad discoloration was minimal. With increases in dosages up to 10 megarad the sample turned green, color intensity increased with higher doses. During experimentation, a “fading” effect was observed. [18] Ethylene Oxide Resistance (EtO): Standard tests performed on Dow Chemical Magnum 2642 (natural low-gloss ABS) ASTM Type 1 tensile bars after EtO sterilization have yielded the following results: Samples retain impact properties and tensile yield strength after EtO sterilization. A decrease in tensile elongation is seen; however, the significance of the change is masked by large standard deviations.
