Plasticware Technical Information
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
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
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
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
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
Polyethylene Terephthalate Glycol (PETG)
- Transparent semi-rigid polymer
- Narrow temperature range -40 to +70ºC
