questions that is not covered here...

1. How do you provide quality ceramic microspheres to us?

We have the following four aspects in which we do our best to deliver 100% quality approved products.

Raw Materials - by selecting the best suitable sources of materials that is both consistent in quality and cost effective, all of our purchasing staffs are required to be aware of updated information and circulate memo to all concerned staffs.

Processing & QC - by continuously investing on improvements of processing units and keeping track of updated technologies of similar products in the industry our engineers have been proud of their proprietary techniques in acquiring the 'engineered products'. Strict rule of quality inspection is another step of obtaining consistency in quality.

Packages & Delivery - All products are packed and sealed right in place of processing units to avoid contaminants. Our logistics staffs will look after each delivery and shipment for your purchase to assure goods are delivered to your required destinations.

After Sales Services - Contact our engineers for any issues concerning our products or value added services you may require. They'll get back to you within 24 hours.

2. What is the lead time from placing order to shipment?

It normally takes us two to four weeks to process and deliver goods depending on our workloads and shipping situation. There are busy and slack season at times around the year. So we recommend you to plan and purchase earlier and long term.

3. Which sea port is the nearest port to your factory?

Tianjin Xin gang port is the loading port closest to our factory. Which is about 120km from our factory. For full container loads we bring truckers in our factory to collect products. For less container loads we deliver the pallets to port.

4. What do you mean by true density?

True density to the hollow microspheres refers to the mass per volume covering spheric wall and its hollow space. This density is also called 'effective particle density' or 'specific gravity'. We test this density by Pychnometer using nitrogen gas at a low pressure of 17psi. Under which the nitrogen gas would penetrate into the spheres with faults. In general, the more faults the spheres contains the higher the true density they would possess.
