Greenhouse Thermoforming 105 Cells Large Germination Plastic Seed Tray
The adjustable humidity dome can adjust the temperature and humidity of the seed environment to keep the soil moisture content and heat in balance.
Provide good environmental conditions for seed germination and seedling growth, and improve plant survival rate.
Material Suggestion For Your Products:
When choosing a plastic, you'll need to consider application. Will your product be used inside our out? Will it be exposed to
extreme heat or cold? Does the product need to withstand high impact? Are you looking for something that's fire retardant?
As a general rule of thumb, we work to the following guidelines.
The following chart provides additional information about various plastic materials and their uses.
| plastic material | advantage | disadvantage | industry example |
| ABS (Acrylonitrile Butadiene Styrene) | Engineered plastic that can be customized to desired levels of stiffness, hardness, heat deflection, and many other characteristics | UV sensitive – requires a UV protective cap layer for extended exposure | UV sensitive – requires a UV protective cap layer for extended exposure |
| PS(Polystyrene) | Clear plastic, very moldable, inexpensive, recyclable, high chemical resistance, high electrical resistance, heat distortion ~200°F | Cracks and breaks easily | Disposable cups, disposable applications, decorative applications, electrical applications |
| HIPS (High Impact Polystyrene) | Very moldable, relatively inexpensive | Very moldable, relatively inexpensive | Picture frames, shower walls, food containers |
| PVC (PolyvinylChloride) | Very high chemical resistance, stain resistant, stiffer than ABS, high room temp. impact strength, natural flame retardant qualities | Difficult to process | shower surrounds, moldings, kick panels, display cases |
| Polycarbonate | Extremely high impact resistance, high clarity – good for transparent parts, precision molding, good insulator, high heat distortion point ~270°F | Low chemical resistance to certain substances (oil, gasoline, harsh chemicals), can be difficult to process, higher material and processing cost | Visors, plastic guards, transportation components (headlights, taillights, instrument panels), appliance drawers, skylights |
| Polycarbonate/ABS | When compared to true polycarbonate – less expensive, lower heat distortion ~240°F, much easier to process, higher chemical resistance | When compared to true polycarbonate – reduced clarity, lower heat distortion ~240°F | When compared to true polycarbonate – reduced clarity, lower heat distortion ~240°F |
