What Are Main Applications of PP T30S?
>> Woven Bags
After drawing and weaving, the woven bags made of PP T30S are wear-resistant, tear-resistant, and have high load-bearing capacity, specially designed for packaging heavy objects such as chemical fertilizers, cement, grains and industrial raw materials. Its tensile yield strength of 30-35MPa ensures that the woven bags can bear heavy loads without breaking, and the uniform fiber formation makes the woven bags have consistent thickness and strength.
>> Flexible Intermediate Bulk Containers (FIBC)
PP T30S is an ideal raw material for producing flexible intermediate bulk containers, which are widely used for storing and transporting powdered, granulated or bulk products in industrial and agricultural fields. Its excellent tensile strength and toughness ensure that the FIBC can bear large loads without tearing, and its chemical stability makes it suitable for packaging chemical raw materials, minerals and other products.
>> Ropes & Twines
Thanks to its high tensile strength, wear resistance and toughness, the ropes and twines made of PP T30S are lightweight, water-resistant, and not easy to rot. The ropes are suitable for fisheries, agriculture, logistics, construction and other fields. Its stable mechanical properties ensure that the ropes and twines have long service life and can withstand harsh outdoor environments.
>> Carpet Backing
In the textile field, PP T30S is used for producing carpet backing through drawing and non-woven processes. Relying on its high isotacticity and low ash content, the carpet backing made of PP T30S has high stiffness, tensile strength and wear resistance, which can effectively support the carpet surface and improve the service life of the carpet.
>> Geotextiles
The geotextiles made of PP T30S have excellent tensile strength, water permeability, and corrosion resistance, and are widely used in road construction, railway construction, water conservancy projects and soil and water conservation. The drawability of PP T30S ensures that the geotextiles have uniform fiber structure and stable performance, adapting to the harsh outdoor construction environment.
>> Concrete Reinforcement
These fibers are added to concrete to improve the toughness, crack resistance and impact resistance of concrete, preventing concrete from cracking due to shrinkage or external force. The fibers made of PP T30S have good compatibility with concrete, and their high tensile strength and durability ensure that they can effectively reinforce the concrete structure.
What Are Excellent Performances of PP T30S
>> Excellent Drawability & Processability
PP T30S has a moderate melt flow rate (MFR) of 2.9-3.5 g/10min (tested at 230℃/2.16kg), which perfectly balances fluidity and mechanical strength. This MFR range ensures smooth melt flow during drawing, easy orientation of molecules, and uniform fiber formation, without the problems of breakage or uneven thickness. The processing temperature for drawing is controlled at 160-220℃, and the drawing process can be completed with simple parameter adjustment, reducing production costs for enterprises.
>> Stable Mechanical Properties
PP T30S has excellent mechanical properties that are tailored for drawing applications, with a tensile yield stress of 30-35MPa and a tensile breaking stress of 39MPa. These performances ensure good load-bearing capacity, wear resistance, and tensile strength for fibers and woven products. Its elongation at break can reach 590%, and the flexural modulus is not less than 1100MPa, which makes the fibers, woven bags, ropes and geotextiles made of it have good toughness and impact resistance, and are not easy to break or deform during use.
>> Good Chemical & Thermal Stability
PP T30S has excellent chemical stability, and is resistant to most acids, alkalis, salts and organic solvents, making it suitable for harsh application environments of its core drawing products, such as woven bags for chemical packaging, outdoor geotextiles, and concrete reinforcement. Meanwhile, it has good heat resistance, the heat distortion temperature is higher than 100℃, and it can maintain stable performance under high temperature conditions during drawing processing and long-term use, which is suitable for products that need to withstand a certain temperature.
>> Cost-Effective & Environmentally Friendly
As a dedicated drawing-grade PP resin, PP T30S has a moderate price, which is more cost-effective compared with special PP grades, and can effectively control the production cost of enterprises engaged in drawing products. At the same time, it is a recyclable material with good chemical and thermal stability, which can be converted into recycled particles through professional channels after being discarded, and reused for producing low-grade drawing products, realizing secondary utilization.
