Huaxin Thermal-field Materials
浙江华炘新材料科技有限公司
Huaxin supplies carbon-fibre insulation, graphite, carbon/carbon and SiC-coated parts for high-temperature furnaces, and photovoltaic crystal pulling is one of the applications it names. PAN sandwich felt and pitch-based boards are listed as separate products, so pick the fibre precursor, the build and the surface finish in your enquiry.

Company scope
What the company makes
Huaxin trades for 浙江华炘新材料科技有限公司, a Huzhou company producing thermal-field materials. Its company site lists photovoltaic crystal pulling and coating among the furnace applications it serves. The English catalogue offers PAN sandwich rigid felt, pitch-based boards and cylinders faced with carbon cloth, viscose-based boards, soft graphite felt and further carbon-based families.
In its preview for the Shanghai heat-treatment and industrial-furnace exhibition, Huaxin explains how the material is made. Formed carbon-fibre blanks are carbonized, graphitized and purified, and a surface treatment is added when the customer asks for one.
The PAN sandwich entry names the construction and shows photos of the boards. Its introduction and model fields are blank, so grade, sizes and thermal figures have to come with the quotation.
Huaxin's contact page places the company in Changxing, Huzhou, while the site footer prints a Hangzhou address. Ask which site will produce your order. The strongest enquiry pairs that answer with a controlled insulation drawing, the material grade and a batch inspection plan.

PAN sandwich rigid felt for thermal-field enquiries →
Huaxin's PAN sandwich rigid felt is a carbon-fibre insulation board for furnace hot zones, pictured as rectangular boards. Huaxin names photovoltaic crystal pulling as an application. The entry lists no density, purity, conductivity or temperature figures, so quote from your drawing and… [2]
Specifications & selection questions →Catalogue families
Huaxin's thermal-field material families and what to specify for each
| Catalogue family | What Huaxin shows | What to put in your enquiry |
|---|---|---|
| PAN sandwich rigid felt | The PAN sandwich name and a board photo | Grade, layer and face build, thickness, density and toleranced dimensions. |
| Pitch-based rigid felt board | Its own entry, titled as faced with carbon cloth on one side | Which face meets the heat, the material record and the furnace position it is approved for. |
| Rigid felt cylinders | Shaped insulation listed as a family of its own | Inner and outer diameter, height, seams and fit inside your hot zone. |
| Graphite, C/C and SiC coatings | Separate families at company level | The actual part, its substrate and treatment, and acceptance for each lot. |
The PAN entry gives no operating temperature, impurity or conductivity figure, and the photo carries no dimensions. Ask Huaxin for a grade sheet and a drawing. [1][2][3]
Markets beyond PV
Semiconductor crystal growth, optical-fibre work, sapphire and heat treatment are also on Huaxin's customer list. Write the PV insulation order on its own terms, since a grade that suits another furnace type may need different properties in a crystal puller. In a PV plant the crystal puller is the first machine of wafer processing, and this insulation lines its hot zone. [1]
How the felt is made
Choose the finished surface together with the grade
Production route
According to Huaxin's exhibition preview, PAN, pitch and viscose fibres are first formed into shape, then carbonized, graphitized and purified. Ask for the process details, inspection limits and lot records that apply to the PAN sandwich board you buy. [5][2]
Surface options
OS coating, graphite-paper facing, CFC facing and SiC coating are offered to suit each customer. Name the finish you want on the drawing and in the quotation, and ask Huaxin to explain what its OS coating consists of. The catalogue photo shows one board, so it tells you little about which treatments a given order includes. [5]
Before the first order
Settle the producing site, the drawing and the lot records
Clarify the two addresses
The contact page gives Changxing County, Huzhou, and the footer gives an address in Qiantang, Hangzhou. Ask Huaxin which is the registered office, which is the factory and which handles correspondence, and request current documents for your order. [4]
Approve the hot-zone drawing
Mark the furnace position, insulation envelope, supports and handling limits. Your furnace or process engineer should sign off dimensions, tolerances and interfaces for any replacement hot-zone part.
Tie records to each batch
Link grade, finished surface and the agreed inspections to every lot. Name the precursor, binder, purification, facing or machining changes that would send the material back through qualification, and ask for records on the parts actually delivered. [2][5]
Project fit
Match the offering to your project
Crystal-pulling operators who need insulation made to a drawing for a known hot-zone position.
Buyers ready to qualify grade, finished build and inspection under their own furnace conditions.
Confirm before ordering
- Grade data for the PAN sandwich board: thermal conductivity, density, impurity limits, temperature duty and a finished drawing.
- Which of the Huzhou and Hangzhou addresses belongs to the contracting entity, and which is the factory.
- Lot performance records or PV furnace trial results, if your approval process calls for them.

Can the pitch-based board stand in for PAN sandwich felt?
They are two products, listed with different precursors and builds. Ask for a data sheet for each grade and compare them side by side. [2][3]
What maximum furnace temperature does the PAN board take?
The entry gives no temperature figure. Ask Huaxin to rate the quoted grade for your furnace atmosphere and operating cycle. [2]
Do the boards come with every listed coating?
Coatings and facings are options chosen per order. The quotation should name the exact build you will receive. [5]
Which address is the factory?
The contact page and the footer give different cities. Ask Huaxin to name the producing site and the contracting company, with current documents. [4]
