To assist recycling, the Plastic Bottle Institute of the Society of the Plastics Industry (SPI) devised the system to mark plastic bottles by type. You'll see a triangle with three "chasing arrows" encasing a number corresponding to the plastic type: PETE, HDPE, PVC, LDPE, PP, PS, and OTHER.
Read below to find out how, through team effort, our customers were able to reduce weight, increase efficiency, and save money.
1:Chemical nucleation in foamed sheet for semi-rigid food packaging results in lower equipment costs, reduced direct gas volume and lower emissions.
INDUSTRY : Leading Food Packaging Manufacturer
FINANCIALS : Reducing emissions while retaining properties and low production cost.
CHALLENGE : Understanding performance enhancements with chemical nucleation versus particle nucleation (e.g. talc).
- Reduced amount of butane by 20%
- Maintained 15% weight reduction despite reduction of butane
- Maintained physical properties
- Saved significant resin cost per unit
- Both extruder and thermoforming throughput rates increased by over 20%
2:Foam Pipe company lowers overall costs, improves physical properties and reduces scrap and rework.
INDUSTRY : Co-extruded foam pipe
CHALLENGE : To save overall costs and material by-product to meet new governmental regulations for sustainability standards.
- Achieved 6% greater reduction in density over an alternative foaming process
- Achieved a 9% net savings in resin cost
- Increased extrusion rates and lowered direct equipment operating costs per foot by 20%
- Reported an improvement in physical properties
- Consistency of SAFOAM®/SAFTEC® reduced scrap and rework
3:Wood plastic composite compounder with a goal to improve performance of their decking products finds multiple, unexpected benefits.
INDUSTRY : Composite decking
QUALIFIER : Looking to increase wood content (MDF) in PVC composite
CHALLENGE : Increasing the percentage of wood increases the water absorption.
- Measured 30-40% less water absorption as measured by 24 and 48 hour water soak standard ASTM tests.
- Increased wood content by 35%
- Increased tensile, flexural and compressive strength by 20-25% according to ASTM standards
- Benefits were achieved with less than 1% of SAFTEC AS applied directly to the wood flour.
