A backpack buckle, also known as a backpack fastener or backpack clip, is a device used to secure the straps of a backpack together. Backpack buckles come in various sizes, shapes, and materials, but they all serve the same purpose of keeping the backpack straps securely fastened.
The most common type of backpack buckle is the side-release buckle, which consists of two parts that snap together to form a secure closure. One part of the buckle is attached to one strap of the backpack, while the other part is attached to the other strap. To fasten the buckle, you simply push the two parts together until you hear a click. To release the buckle, you press a small tab or button located on one of the parts.
Other types of backpack buckles include ladder lock buckles and tri-glide buckles. Ladder lock buckles are often used to adjust the length of the straps on a backpack, while tri-glide buckles are used to secure webbing or straps.
When selecting a backpack buckle, it’s important to consider the size and width of the backpack straps. The buckle should be strong and durable enough to withstand the weight of the backpack and its contents, and it should be easy to fasten and release.
Acetal is a crystalline thermoplastic polymer material & bridges the gap between metals and ordinary plastics with a unique combination of creep resistance, strength, stiffness, hardness, dimensional stability, toughness, fatigue resistance, solvent and fuel resistance, abrasion resistance, low wear and low friction.
Acetal has excellent flexural memory and property retention when subjected to repeated loading.
Physical properties remain consistent across a wide range of temperature, relative humidity, and weather conditions.
What is the characteristic of Nylon66?
Nylon 66 is a thermoplastic polyamide resin & the most versatile of plastics.
– Easy to process; easy to modify to meet specific needs, environmentally responsible in production and in reuse.
It’s tough, light and surprisingly resilient in hot, chemically aggressive and humid environments.
This material maintains good tensile strength, chemical resistance, stiffness and flexural memory.
Nylon is excellent in high temperature applications.
However, a hydroscopic resin, therefore, physical properties will vary as the relative humidity changes.
When dry, tensile strength is higher and impact is lower. When wet, tensile strength is lower and impact strength is higher.
What is the characteristic of PP (Polypropylene)?
PP is most popular & cheap material used for general injection. Use this material where load bearing and impact are minimal. Another advantage is that the material offers a very soft feel for side release buckles, which is ideal for children.
What is the characteristic of PC (Polycarbonate)?
PC is an Engineering Plastic with superior physical characteristics, notably Transparency, High Impact Strength,
And High Heat Registance.
This polymer is highly transparent to visible light and has better light transmission characteristics than many kinds of glass.
PC is stronger, usable in a larger temperature range but also more expensive than other Engineering Plastics.
