Core Trays manufactured with RECYCLED PLASTIC

Core Trays manufactured with VIRGIN PLASTIC

Pricing

Cheaper price as manufactured using regrind from domestic or factory plastic waste. There is no way to tell how many times an item has been recycled (heat history) before and the actual makeup / chemical composition of the raw material itself.

Virgin material is 47% more expensive than Re-cycled and has been polymerised from natural gas or crude oil which has never been used or processed before. Most importantly it is made of the known source.

Lifespan

Prediction of 5 years lifelong.

Track record of plus 25 years lifelong.

Eco-friendly

Membranes made from recycled materials have a lower safety and strength rating e.g. mechanical properties. These products break down and leave microplastics in the soil with no one being held accountable for the clean-up. The plastic polymers are weakened by around 10% each time going through the heat process (heat history) which shortens the polymer chain and makes the plastic more susceptible to breaking and failing as the mechanical properties have been eroded.

Products made from virgin plastic can withstand greater UV attack as experienced, used and handled in the field. Resistance to UV is a vital requirement for core trays given the nature in which they are often stored in full sunlight. Therefore Virgin Plastic Core Trays are fit for purpose.

Quality

A piece of plastic can only be recycled about 2-3 times before it's no longer be usable due to the significant reduction in mechanical strength e.g. impact. In order to strengthen these recycled materials, some virgin plastic will be added, unless advertised as made from 100% recycled materials, even her impact modifiers are used to artificially bolster the mechanical properties which contain toxic chemicals, not great for the environment and can contaminate valuable core samples.

Products made from 100% virgin plastic, in this case, a polyolefin e.g. polypropylene approved for food use, non-toxic chemical, in fact very inert chemically hence it's food rating and clearly suitable to store core without interference in the chemical makeup when conducting ASSAY. 

Strength

Impact strength of 2.2 kJ/m2 is nearly 'A that of the virgin copolymer of the correct grade. The thin walls of a core tray will become brittle which will result in jeopardised the core. Aside from losing these vital pieces of core, it would cause an additional cost for manpower to re-box the cores into new trays which also jeopardise the health and safety of your team. Is the saving real or only in actual fact perceived?

Impact strength of 8.5 kJ/m2 for a polypropylene copolymer 20 melt flow.

Plastic memory as per thermoplastics is the ability to return to its original form when heated and or pressure applied. Recycled plastics exhibit increased plasticity and processability due to a reduction in molecular weight e.g. reduced crystallinity which makes them more attractive for some temporary products such as shrink-wraps and packaging. Recycled plastic also works particularly well for bulky heavy wall products such as children's playground equipment, building materials, park benches, decks and outdoor furniture. These products are manufactured with up to 50mm thickness and their lifespan is 20-25 years. It should also be noted UV attack is a surface effect, heavy wall products can better resist UV degradation, thin walls cannot.

Core Trays are manufactured with nominal 2mm wall thickness and only rime virgin plastic can provide this quality e.g. superior mechanical prime - core trays made from prime virgin PP have a proven track record tested life span of plus 20 years.
