Plastic Resins

Plastic Resins

Listed below are the primary resins used in the manufacture of our products. Following are some of the characteristics and features of these resins. Also listed is the Plastics Industry Associations (SPI) resin identification code number.

	Polyethylene Terephthalate (PET) Translucent semi-rigid to rigid polymer Narrow temperature range of -10 to +60ºC Not autoclavable Moderate chemical resistance High impact strength Typically used for dropper bottles and media bottles		Low Density Polyethylene (LDPE) Translucent flexible polymer Narrow temperature range of -50 to +80ºC Not autoclavable Good to excellent chemical resistance Robust and virtually unbreakable Typically used for dropper bottles, pasteur pipettes, storage bottles and wash bottles
	High Density Polyethylene (HDPE) Translucent rigid polymer Broad temperature range of -100 to +120ºC Good to excellent chemical resistance High tensile strength making it very tough Typically used for bottles		Polypropylene (PP) Translucent rigid polymer Temperature range -20 to +135ºC Autoclavable at 121ºC Good to excellent chemical resistance Resistant to fatigue making it tough Typically used for beakers, bottles, caps and cylinders
	Polyvinyl Chloride (PVC) Rigid polymer Narrow temperature range -25 to +70ºC Not autoclavable Moderate chemical resistance Rigid or flexible, coloured or clear Typically used for cap liners, trays and troughs		Polystyrene (PS) Transparent rigid polymer Narrow temperature range -40 to +90ºC Not autoclavable Moderate chemical resistance Brittle yet has excellent clarity Typically used for containers
	Polycarbonate (PC) Transparent rigid polymer Broad temperature range -135 to +135ºC Autoclavable at 121ºC Moderate chemical resistance impact strength Typically used for bottles and safety shields		Polytetraflouroethylene (PTFE) Opaque rigid polymer Wide temperature range –200 to +260ºC Autoclavable at 121ºC Unrivalled resistance to almost all chemicals Extremely low friction coefficient Typically used for bottles, beakers, cap liners, septa and stirrers
	Polybutylene Terephthalate (PBT) Opaque rigid polymer Wide temperature range -40°C to +180°C Autoclavable at 121°C Mechanically strong engineering polymer Good resistance to chemicals Typically used for screw caps and connectors	SRS001	Polymethylmethacrylate Acrylic (PMMA) Transparent rigid polymer Narrow temperature range -60 to +50ºC Not autoclavable Moderate chemical resistance Very tough and high clarity Typically used for radiation shields
	Polyethylene Terephthalate Glycol (PETG) Transparent semi-rigid polymer Narrow temperature range -40 to +70ºC Not autoclavable Moderate chemical resistance High impact strength Typically used for media bottles		Polymethylpentene (PMP) TPX Transparent rigid polymer Broad temperature range -180 to +145ºC Autoclavable at 121ºC Good to excellent chemical resistance Has a low density and a high clarity Typically used for beakers and cylinders
